I agree that we should provide some API-level gem functionality that 
may or may not be required for the core gem tools themselves.  I'm 
guessing there won't be a *ton* of these things, but you've obviously 
come up with a good one here.  Probably need to have a separate require 
for this kind of stuff so it doesn't end up getting loaded during the 
more typical usage scenarios.  I say go ahead and include it!
