Definitely worth it, list mimics of what is in pg_dump are located in
pg_basebackup, and since a 9.6 patch in psql as well. That's as much
code duplication.

Preventing the use of elog in the frontend is something that has been
addressed multiple times with FRONTEND, so that's not likely going to
be an issue I think. Andres has mentioned as well having some elog
stuff available in frontend..
