Indeed, I just looked that up.
I'm quite disappointed we agreed to that, but I don't really want to
have to go over the archives again.
It's curious that this has come up now, because I've been merging
patches on this basis for months now :-)

It is easy to argue that 'getting reviews is easy', and that has been
put often. I would argue that it doesn't matter how easy it is to get
reviews, that getting reviews is killing the joy of working on Samba.
Certainly by this graph *something* happened in October 2012:
As a professional software developer, as long as the process keeps
working (and I have come very close a number of times to saying that it
isn't working, and opting out), I'm currently willing to continue in it.
I do feel very sorry for those who don't have all day to contribute to
Samba however, because this process tipped me over the edge to make
other changes in my professional arrangements now that working on Samba
has become so much less enjoyable.
I would also argue that the 'clean and simple' rules we have applied so
far have made Samba worse, not better. That even doc/comment typo fixes
go up for review (let alone the double-review to get into stable)
creates work, and certainly in my case means I don't bother pro-actively
fixing 'little stuff' any more, because it isn't worth writing the
change, and spending even longer writing the mail, chasing up for review
That, in the case of external patches, for the benefit of 'clear and
simple rules' we put aside totally the experience and trust in members
of the Samba Team to decide 'this patch doesn't need more than my
review' seems totally wasteful.
The resource of developer enthusiasm is not infinite, and we should be
incredibly careful not to drain it except when absolutely required. We
should ensure our processes uplift our developers, be they on the team
or off it, rather than make them feel they have to work past an
obstinate policy system that only costs everybody time.
We should do this because if we burn off developers early, they won't
come back, but if we encourage them early, we can look forward to many
more contributions, and this is what will make Samba grow again.
