[ I'm curious which definitions of `compat` this uses.  ]

Hmm... isn't the `(lm-maintainer)` right after `:maintainer` erroneous?
[ BTW, I think Jonas has another change pending for this code.  ]

Why not just replace (make-separator-line) with
(if (fboundp 'make-separator-line) (make-separator-line) "")?
`newline` is a command and I think it's preferable not to use it
from ELisp.

I'd use

    (if (fboundp 'custom--standard-value) ;; Emacs≥27
        (custom--standard-value (car ent))
      (eval (car (get (car ent) 'standard-value)) t))

so the code "speaks for itself".
