How important is Python 1.5 compatibility?

[Erik Max Francis]

How important do people think Python 1.5 compatibility is?  For some of
my projects I've strived to keep it compatible with 1.5 (at least for
the portions of the applications that actually would work with 1.5; for
instance Unicode support obviously requires Python 2.x).  It seemed to
me that this used to be fairly important, when, say, 2.1 was new, mostly
because of other large Python applications that required 1.5, or lazy
ISPs who still used older version.

Based on the discussions I've seen, I'm getting the impression that this
is less and less the case as time goes on (which is, of course, exactly
how you'd expect things to be).  How important is Python 1.5
compatibility today?
