What's the alternative?

Have each user create their custom domain?

Is there a stable subset that we could maintain with minimal effort?

Would it be better if the module were removed from PostgreSQL core but
maintained externally where it can iterate faster and keep the database
up to date?

Is there a third-party library that does maintain such a database so
that this module could be based upon that instead of having to maintain
the database itself?
