Putting them in svn should be fine; if there's no tag it won't get
published.  Alternatively, you could upload them to your bitbucket or
github account for the time being.  Then when the CR is accepted
move them to svn (or simply publish them from your account if you want
to maintain them yourself).

Sure, that's fine.  Perhaps if we ever decide to fix it properly, we
can provide a hook for the egg to use.
