As I read it, Jonathan is proposing to move (centralize) some pieces of the Koha development ecosystem that are already handled in such ways, but disseminated in personal github/gitlab accounts. I agree with his proposal, and I like the fact that we can move all the issues along with the repo :-D (one of my issues with moving kohadevbox, that has more than 200 issues on its own).
I also think Mark has a fair point regarding the QA process (even tough we are already working like that for those projects), and I'm sure this is a good chance to explore new additions to our workflow, and how our rigorous QA process can be adapted without loosing the abilities we already have.
Awesome, Jonathan. Good one.
+1 from me :-D
