IME, `condition-case-unless-debug' is used/useful mostly for
`condition-case` that catch "any error", most of which might be better
served by something like `with-demoted-errors`.
For those `condition-case` which catch one particular kind of error to
handle a particular expected situation (e.g. when catching `scan-error`
around a call to `forward-sexp`), `condition-case-unless-debug` rarely
makes sense.
