I can think of a couple of ways offhand about how the information schema
could be extended without breaking the SQL standard. You could just
add columns where needed. Or you could add tables that are joined to
the standard tables and contain the extra information. Or you could
create a "information_schema_2" that contains a copy of the original
information schema with the extra information added somewhere, so users
can easily switch back and forth.
If you look closer, there isn't really all that much that cannot be
gotten from the information schema. Figuring out exactly what that is
might be instructive before deciding how to go forward.
