Just to crosspost here, I just found out today about this extension.
The general feeling I got from various conversations is just go for it - get something done and lets see how it works out.
Dave seems to agree its a good idea overall, perhaps others want to chime in.
I say, let us first finish off a quick master list of pass/fails for non core packages, then lets try a couple of run throughs for FEATURE testing even before we finish INSTALL/UNINSTALL testing.
Thoughts?
