I'm pretty sure regex has backward compatibility as a goal for just this
reason (so it can replace the current module).

I disagree with this with respect to 380.  Haven't looked at the others.

As I recall, the actual decision was "at *least* 5 years".  It's only
been one so far...was the discussion that five years was too short or
too long?

As the code bases continue to drift apart, and we fix the fixable bugs,
the number of patches going in to 2.7 will decrease over time, so I
don't think the burden of continuing to support it will be too heavy.
Currently about half of the non-feature-request issues (ie: bugs) in
the tracker are tagged 2.7.  I expect to see that percentage continue
to decrease over time.
