I am not aware of any problem there - is there an issue anywhere about it? If not, would you please care to enter one?
The only other downside I see is documentation.
Good news here is that this is heavily under construction now.
I guess I’m just used to 1.8
Please note that you should be able to use 2.0 just the same way you are used to on 1.8. You do not need any discovery & things & Paper UI at all - just use your 1.x bindings exactly as always before and do everything in a textual configuration.
