The long and short of it is that the feedback is "We don't want to fix shit" from themers and "We don't care if shit is broken" from users, not just in this thread, but in multiple other threads since Beta 4.
If you check the date on the post in the dev forum, you'll see that it's from July. In addition to the dev forum post, I posted on ZIV to point themers there towards nightly builds and suggest using them for the feature.
Nobody who is not a dev said anything until Beta 4 was released.
Since then, there have been several threads of people less polite than you complaining about it, and not a single non-dev themer coming forward in support of it.
I find it extremely irritating when people choose to do things the wrong way, and I think mistakes should be fixed where possible, thus my hard-line stance. But in the end, people are against it and it's becoming clear that its outright harmful to the health of SM5, so I'm backing down.
Here's a screencap of a facebook thread on the topic. (bonus joke: Aldo posts a fake solution that breaks everything. He's a masterful troll, good thing nobody fell for it.)
