What you've done here is to take two comments about two different things, pulled them from their context and edited them together as though they refer to the same subject. The first refers to your claims that ST lighting control is dependent on cloud connectivity, which means that you lose the ability to control your lights in the event of cloud/internet failures, which is untrue.
The second refers to the claim that it "isn't possible" to do things like access the Hue transitionTime property without the Hue Bridge, which is also untrue.
To me it is the same thing. I can't use Hues the way I want with the SmartThings hub locally. You can take it apart for the sake of argument by saying the car will still go without gas. But I don't just want to go downhill.
I'm not an Apple user, so I don't know anything about iRule and did not make any claims about it. I also didn't claim that Tasker communicates with my lights locally.
So "Ditto all of those things and my ST Hub" was just an oversight. See, you are fallible. (c;
But now that you mention it, I see this note from AutoHue (the Tasker plug-in for Hue):
"Hue Note: For the Hue lights the app only works on your local (WIFI) network, this is currently the case due to a restriction in the Hue API."
So, local access...but ONLY local access. Bummer.
While I don't use the plugin, all Hue API access is local. If I need remote I use the Hue app or SmartThings, but there is usually no need for remote access to lights.
By the way, I find it interesting that you've gone from this...
Putting all of your eggs in a SmartThings basket (or any kind of singular controller) makes for fewer options (why open the painfully slow SmartThings app when I can just tap a shortcut on my phone's home screen), and a complete teardown/rebuild should something go unsupported.
...to an argument that's centered on just how much you've built up around and are dependent on one specific controller: The Hue Bridge.
Shouldn't be all that interesting. I use what works best; in this case the bridge. In fact, the SmartThings hub almost never talks to the Hue integration (I think I have one app that shuts them down after a power failure - but that could easily be moved to a shell script - and probably will now that I think about it). The only reason I keep Hue Connect around is for remote access, and I can't recall ever using it. Frankly, everything I could pull from SmartThings I have. Only the Echo has refreshed my interest in it as a means to get commands to my server via virtual devices.
SmartThings has been a mess for an awfully long time. Why just this morning, after the big platform fix rollout, automated things weren't automated due to my morning routine not executing. I have seen these types of glitches regularly for the past two years. So my conclusion is that it is not reliable, and I don't want my lights dependent on it, especially since "I" can not achieve local operation due to me having my own code. Add to that I believe Samsung will eventually ruin it, or kill it in its current form.
I suppose if all you want is to turn white lights off and on, what you have is fine. But most Hue users I have met prefer color, and do creative things with them. I have dozens of scenes involving dozens of lamps, and I like to change things up. Compare editing a shell script to having to change those same settings in the mobile app (yuk).
So, the things I do with Hue, are far simpler to achieve using the local API, and far easier to control using various tools on mobile that can communicate with it directly as opposed to oAuthed endpoints on the physical graph. To me, having the bridge offers up way more than not having it. Folks who go your route cut themselves off from much of the Hue echosystem including Tap and third party apps (and who knows what else is coming), and effective mobile control. I see little merit in the downside you site, and feel strongly that the average Hue user won't either.
Anyway, feel free to have the last word... ScottinPollock has left the building. (c;
