In this specific case, I believe the Ceilometer folks are adding, or
actively working on adding, pieces to Oslo that match the work they did
on the new Pecan-based WSGI router framework. I think the reason that
they use Oslo now is because they copied in a whole chunk of Nova code
to begin the project -- for expedience's sake -- and then after working
with the Oslo team saw that it would be cleaner to use Oslo and
contribute fixes back into it. Ceilo contributors, please correct me if
I am wrong!

Shunned? No. Encouraged to align, yes. :) As you know, it's a pet peeve
of mine to see duplicated code, so I take special note on things such as

I totally understand the pressure to get things working and make
progress, trust me. :) This was merely a gentle nudge to remember that
there is benefit in code re-use that often trumps short-term gains in

All said with the deepest respect and reverence for your work, Sandy :)
