I think (meanwhile) that this is not enough to justify the replacement of a
component. Replacing a Zope 2 component always caused some pain. So as a
rule for replacing something in the Zope 2 core we consider those rules:
- the replacement solves existing functional problems
- it adds major functional benefits
- no issues with backward compatibility, well tested etc.
For the Zope 2 core we must be very careful about changing stuff. Stability
and backward compatibility are much, much more important for the end-user
than satisfying our replace-all-with-something-better drive :-)
Don't get me wrong but we've done some minor mistakes with replacing stuff
in the past and because of that I became a bit conservative about changing
things. Of course I am only speaking for the Zope 2 core.
