I hear you.

But we have waited for way too long for better CI. I see great efforts in that direction.
But I personally do not want to wait any longer to make a move.

We do open source, we should have fun, take risks, move fast, fail fast, recover etc….

so let's JFDI

Is there really a difference between creating a 4.6 and doing what you say, and tagging master
(start) and doing it on master leading to 4.6 release ?

Assuming the QA does not improve, 4.6 would not be worse than 4.5. If we can improve a bit
on the QA then we win.
Plus I think a different commit model will help a lot in quality.

We can do this proposal on email..and once we have consensus write it up for archive in the
wiki.
If we move to the wiki now, this effort is going to die.

if we have consensus no need for vote.
