Really important.  When I add an external to a trunk/branch version of
something as I need to fix/improve something, I immediately change the version
requirement in the setup.py.

What's better? Do a "my.package > 2.7" or leaving it at "my.package >= 2.5"
and trusting your memory to change that afterwards?

You'll surely see the "my.package == 0" when releasing (as stuff breaks),
which means more work as you have to look up version numbers again.

Make it easy to do the right thing instead of making it more work, I'd say.
The '0' means it is easier (human nature...) to just leave the version
requirement in the setup.py alone as it is too much hassle.

In case the policy is changed, I'll of course fix up the tool.  I'm still -1,
though :-)

A '0' version does little to help people pitching in with a bugfix.  They'll
have to figure out themselves what the version is supposed to be.

If you pick the my.project/branches/reinout-fixthingy branch and the version
is set to '0', you'll have to figure out what version of the branch is.
A 2.8 bugfix branch? A feature brach off the trunk?

The '0' seems especially unclear for branches.

for i in range(20):
    print "yes, I want a written-down policy, please"
