> I have grown pretty negative opinions of “using a programming language as a config language”

Same here. I like the openbsd approach of small DSL (pf, doas) or just simple ini-like key-value config (sysctl, rc.conf). If you want more, just patch the software and be done with it.

A programming language is OK if the intent is to build a platform (Emacs, Vim) but for something that is purely an application software, it's very much not necessary.
