For all intents and purposes I would consider all parts (past and present) of bioperl-ext deprecated, unless we can find someone willing to take them on.  And, with that in mind, frankly I would be much more amenable to supporting XS (or similar) interfaces to common bioinformatics libraries (Bio::DB::Sam as an example) than ones specifically designed with bioperl in mind.  The latter (bioperl-ext) have significantly bit-rotted to the point I'm not sure whether they would be worth keeping around.
