True.
I think one of the key points here is that different important libs haven't
been ported yet:
https://python3wos.appspot.com/
Too many of them are still marked red and IMO that is the main reason why a
lot of people are being so hesitant, not unicode.
"boto" alone counts as hundreds of thousands potential users which simply
cannot migrate.
Django made the transition only a couple of months ago, which basically
means it's still in a beta state, and AFAIK fundamental projects such as
Twisted don't even have an ETA.
Considering 5 years have passed since Python 3.0 first made it's appearance
I consider this a *serious* delay.

That's likely to apply even if project X is not within the list of your
dependencies, because you may not depend from X now but maybe you will in
the future, either because you need X or because Y requires X in order to
work. It is *crucial* for people maintaining those libraries to put Python
3 porting on top of their TODO list at the cost of not working on new
features.
