The problem you mention here is absolutely *real*.
It's not only a matter of whether all your deps have currently been ported
already.
Software evolves over time and you can also remain stuck later, when you
suddenly decide you need lib X and lib X hasn't been ported yet (uh-oh!
what do I do now?).
And please, note that *as of now* lib X includes names such as Twisted and
Paramiko, which means hundreds of thousands of users which are stuck as we
speak.
How can a company decide to make the switch starting from such an
assumption? The assumption that lib X or Y might not be ported soon, or
even *ever*?
IMHO as long as we won't get close to a 100% of libs being ported the
current situation is not likely to change.
FWIW here's some stats (inspired by recent Brett Cannon's post about
openstack): http://stackoverflow.com/a/22113627/376587
