Same thing I said in '07; I don't have a problem w/ hooks for ebuilds 
to specify additional QA checks, but this *cannot* be the user's end 
solution- it needs to be purely for making it easier for devs to spot 
their screwups.  In other words, revdep-rebuild shouldn't be involved; 
this should spot/complain that zlib (for example) changed abi w/out a 
matching metadata setting/whatever, rather than having checks done in 
the consumers.

Using this for anything other than a QA check of the originating 
package, basically has an end result of us going towards a 
non-deterministic resolution model- which is a clusterfuck, frankly.
