No, it's evidence that *Dropbox* is not ready for Python 3.x. It tells you
ABSOLUTELY NOTHING about the suitability of Python 3.x for other companies
and other users.
Despite your earlier snarky comment about "reiterate", it is clear that you
still don't get it, so I'll say it again. There is nothing wrong with
individuals or companies choosing to stay with Python 2.7, or 2.6, or 2.5,
or 1.5, if it meets their needs. GvR doesn't need to "fight" for Python 3's
He works for a company where, *right now*, a customised version of 2.7 meets
their needs. That doesn't mean that other companies aren't ready for 3.x,
and it doesn't mean that Dropbox aren't preparing for 3.x. They are.
You might think that they could just turn around tomorrow and say, "Right,
as of tomorrow we're using Python 3 for new projects", but that's not how
it works when you're a company running Python on hundreds, maybe thousands
of production servers, all of which will need to have Python replaced
*while running live* before the change over.

These would be the features of Python 3 that nobody needs and nobody wants
because Python 2 is good enough for everyone?
I wouldn't want to guess what the customizations do.
