I say go for it. I'm giving a presentation at the Australian open source 
developer's conference [1] in about six weeks and this will help answer 
the first question I'll get [2].

As Brad says it doesn't impact or break any other part of the framework, 
and if it's in CVS I'm more likely to test it.
