What I didn't get here is that the discussion was about type signatures (my 
thinking was about an API *implementation* that is provided through two modules 
API.{V1,V2} with different signatures). So the question is rather whether the 
V2 system still allows to work with V1 interfaces in a useful way, if not these 
should rather be moved to an adaptor package that is able to translate V1 
signatures to V2 ones.
