This was pretty well discussed back in April and May IMO.
Suffice it to say, I'm very much against the idea of 'disabled features'
landing in trunk, and I'm also not a fan of the idea of an arbitrary max
lines of code per patch set. A number of folks have pointed out that we're
getting better at things like "feature-rush" at the end of a cycle and our
own community "best practices" enforcement on patch size. I think that
model works well in an Open Source environment, particularly one the size
of OpenStack with the varied interest and participation.
IMO intentionally placing non-working (and thereby useless code as far as
I'm concerned) in the project with no testing, no documentation and worst
of all no guarantee that anybody is ever going to work on said code again
is a bad idea. The explosive growth of what OpenStack is and all of the
projects is pretty difficult for folks to get wrapped around already, let
alone if we start having this unbelievable matrix of flags, paralell
Anyway, a number of postings are no longer tracked in this thread it seems,
but there have been statements from Russell B, Thierry and Michael Still
that I strongly agree with here.
By the way for those that want to go back and read the entire thread again
