How about a global config command like:

ip access-list non-wildcard-acl

which will then accept the new format only, (the non wildcard based one), 
defaulting to OFF so that the old format is the common case and backward 
compatibility is there for those who are used to the old way and those who 
explicitly want the new format can opt in to it?

That way you could appease both sides of the argument without breaking a 
thing...   and even store the config in the old format if need be.
