Those are good points except for the second one. On my system at least, and I believe on all systems that provide nonstandard crypt(3) implementations, crypt will detect and use the right hash function if you pass the entire crypted password as the SALT. For example, I have a user with a password "test". His crypted password is $1$V80MC/nB$s/9nJGRaDB3xtUNpI7k0O.. Running this Perl code: 
print crypt('test',
            '$1$V80MC/nB$s/9nJGRaDB3xtUNpI7k0O.'),
      "\n";

prints the correctly encrypted password.
