The problem really is Epic’s “Features over Stability” attitude.

While I’m in the same boat with 4.7.0 and now 4.7.1 not letting me load my project (answerhubbed since Preview 8), I don’t really think Epic has such a mentality.
At first I was a bit distressed that I couldn’t get on 4.7.0 while lots of people seem to be having fun with the new features (better cyclical dependency handling, better UMG!), but those features have been in the works for a long time: it’s only in the last few days that I’ve been able to tell Epic about my problems with their release, and so they’ve only had a few days to work on a solution. The real test of your statement, at least for me, is what happens in the time after release - how good are Epic at post-release support? And heck, with 4.7.1 out already with bug fixes, I’m pretty confident they’re not OK with software that doesn’t work as intended! So I have some faith that fixes will be along, not in 4.7.1 for me, but at some point soon 
Don’t lose hope!
