I don't see it as an exception list. The direction I see for this is
that the parameters to CREATE LANGUAGE are obsolete and will eventually
be removed altogether, with "CREATE LANGUAGE foo" using an existing
template as the only recommended way to do it.

To do that we'd have to force an initdb, in which case we might as well
add the proposed pltemplate catalog and have done with it.
I'm entirely willing to add the catalog if people are willing to accept
an initdb now. As I said earlier, I don't want to mess with adding a
usage privilege just yet, but we could add the catalog with a
nonfunctional ACL column and write that code later.
