I think addressing that would actually be fairly simple in theory.
Move a lot of those DATA lines to SQL initdb scripts. Virtually all of
pg_proc, pg_operator, pg_opclass, pg_opfamily, pg_cast, etc can be
initialized using SQL. Hardly any of the records in there are needed
for bootstrapping.

That would reduce the pain of editing this files *enormously*. The
worst part of adding new operators is making sure all the opclass
entries line up properly. And when there's an OID conflict and they
all have to be renumbered and the opclasses fixed up that's when
they're a real headache.
