I think many up and coming devs have at least touched C somewhere
(e.g. in university). And because it's more critical to the project
and also to many other low level projects, they don't mind learning it
so much if they don't know it yet. But I, for example, try to write as
few Perl tests as possible, because getting good at Perl has pretty
much no use to me outside of writing tests for postgres.

(I do personally think that official Rust support in Postgres would
probably be a good thing, but that is a whole other discussion that
I'd like to save for some other day)

Backporting test improvements to decrease backporting pain is
something we don't look badly upon afaict (Citus its test suite breaks
semi-regularly on minor PG version updates due to some slight output
changes introduced by e.g. an updated version of the isolationtester).
