Actually I'm not very uncomfortable with keeping the unintuitive "md5" 
names and ignore the inconsistence, it's just that I feel if you are 
*ever* gonna change it, now is *really* the time.

Personally I wouldn't protest if you just rename the lot and stop 
supporting old tags and names. But that's just me, I'm the big bang type.

Otherwise you could switch to using gen(xx) for signatures (and 
john.conf names & functions, which you did not mention), but parse 
md5_gen(xx) as meaning the same. I think that would be reasonable though 
maybe not beautiful in the code.

That is, *use* the right side but *allow* the left side:
--format=md5-gen(12)       ==   --format=gen_12
user:md5_gen(0)hhaasshh:   ==   user:gen(0)hhaasshh:
MD5GenBaseFunc__crypt      ==   GenBaseFunc__crypt
