I think that's a good little explanation as to why we have openstack-common, but when did it become a good reason to copy code around via an inclusion mechanism?

Lots of code is in packages (outside of openstack, in pypi and elsewhere) that is also in 'incubation' (in fact, what code isn't in perpetual incubation), that's why u still have version numbers?

I just worry about inclusion of code that isn't versioned into other projects, and I don't see the benefit of that when u can just have a package that has that code as well.

Especially with the work Monty has recently done on versioning and packaging the client libs from Jenkins, I can't see a reason to keep following this "update common and merge to everything else" pattern at all...

Actually http://wiki.openstack.org/CommonLibrary explains it quite well.
In particular:

"openstack-common also provides a process for incubating APIs which,
while they are shared between multiple OpenStack projects, have not yet
matured to meet the [library inclusion] criteria described above."

"Incubation shouldn't be seen as a long term option for any API - it is
merely a stepping stone to inclusion into the openstack-common library
proper."
