These questions are asked by people out there:
And we're unlikely going to attract communities of any of these frameworks if we don't demonstrate that Agorava can be used with them. Thus at least a proper set of tutorials, examples, call them what you want (part of the documentation) will be necessary, otherwise people are likely to use other solutions or develop something similar from scratch.
For those frameworks that (unlike Java so far;-) have a proper module concept already, visibility in such module repositories also would help to gain acceptance and avoid people reinventing the wheel.
