I am not quite sure which interpretation you are refering to in this
case. Back to the Debian Python policy, the wording in section 2.2 uses
"should" instead of "must", so there is room for discussion in
exceptional circumstances I guess.

There you go.

Even better. Or use a virtual environment. Which the majority of
developers do (one or the other).

"Old" indeed, but still actively maintained upstream.

I'll ask the same question again: besides your ITP for Orange, is there
anything *already* in the archive in desparate need for an upgrade of
matplotlib to its new major release?

If not, figuring out a way to support both versions can be postponed to
the next release cycle, imo. I don't see where the rush would be. There
is already enough on our plates as far as RC bugs are concerned.

I have already spoken quite a bit, so I'll let others in the team give
their opinions.

Cheers,
Ghis
