Constraints aren't relations and don't need pg_class entries.

Either of these cures strikes me as worse than the disease. Now that we
have schemas, I don't think that the index name collision problem is
near as bad as it used to be. I'm not eager to uglify the catalog
structure to eliminate the problem.
We'd also be creating some compatibility headaches --- for instance,
DROP INDEX would have to change syntax to include the table name.
