FWIW, the community on Discord is friendly and helpful, including the developers. I got DR on the cheap with a bundle, so my expectations were different than they would have been had I paid full price for it, but then, ostensibly, I also would have been more invested as well. It's "professional" in that it's been used for games on the Switch, but there is the feel of a start-up and you can sense it in the enthusiasm of the folks behind it (and in the armchair psychology you point out with identity and trying to build community). I'm having a lot of fun with it, but yes, there are needed improvements with documentation and on-ramping. I would put more emphasis on http://fiddle.dragonruby.org/
