Because I do it at the same time I carefully review the code myself.
Then I can accept it or not considering my review and the tests.

Yes. But the stuff that constantly breaks is stuff that was never the
subject of a bug, and has no tests.

Apologies, I didn't mean that, and I didn't mean to be rude. Everything
I said (failed assumptions, lower quality, no good code review, broken
stuff that was never a bug, etc) applies to Pharo. Or at least that's
what I see in the Pharo mail list and what I heard from former Pharo users.
