Mostly just "the fastest schedule I think we can manage to pull off."

The current development cycle has gone on longer and drifted further out 
than I'd like, and because of that there's a fair amount of finishing off 
work-in-progress API's and features work to do before we can make a 

It's not entirely unlike having overslept and then scrambling to get to 
work as fast as you can to minimize the damage :) Calling it bad planning 
and release management is also applicable...

Wider-scale testing of HEAD + reporting any oddities would be helpful 
certainly, extra bonus for fixing any regressions found - I'm sure there 
are /some/ regressions the test-suite + our own day-to-day testing hasn't 
caught out.

Ok. Work towards abstracting SELinux specifics out of core rpm into 
plugin(s), enabling use of other similar (security) frameworks to be used 
without changing rpm itself, would be very welcome. Perhaps too late to 
get into rpm 4.9.0 at this point but there's always the next release :)

Makes sense, sure. I basically just wanted to know what aspects of the 
plugin/collection system you're interested in and the above answers that 
quite sufficiently, thanks.
