[Vala] Vala-team PPA packages

[Eric Gregory <eric yorba org>]

Apologies in advance if this is the wrong place to ask about the Vala PPA,
but I was wondering if it would be possible to have a slight policy change.

Currently, only builds of the latest releases of the unstable and stable
branches are kept in the repo.  The problem with this approach is if that
version contains a critical bug, all Launchpad projects which depend on the
Vala PPA will fail to build.

Fortunately there's a simple solution -- keep the previous builds in the
repo.  This way projects which require an exact version of Vala can
continue to build on Launchpad, and end-users can install and "lock" a
specific version of Vala on their system if need be.

Does this sound reasonable?  Is there a reason the PPA is currently not
setup this way?
