One key difference between the tapestry case and what we're discussing
is that there was absolutely no migration path in the tapestry case.
Switching over to using classes in commons functor wouldn't be that
difficult (find/replace?) I would imagine.

Of course, I'm addressing a specific case (collections/functor), but I
do tend to agree that we don't want to go overboard with completely
rewriting something.  In fact, I was one of the loudest protesters
about the T5 stuff (which is also why I'm using Wicket now).  I see
where you're coming from, Stephen.  However, if we explicitly disclose
the expectations up front, perhaps there won't be as much backlash?
