We have some previous experience with this type of thing when we migrated
contrib/tsearch2 stuff into core.  I'm too caffeine-deprived to remember
exactly what we did or how well it worked.  But it seems advisable to go
study that history, because we could easily make things a mess for users
if we fail to consider their upgrade experience.
