Um, other than "show work_mem" or "select from pg_settings"?
The fact is that you cannot know the active value anyway without
checking, because what you did with SET PERMANENT might be overridden
in various session-local ways. The proposal for hand-edited versus
machine-edited files just adds one more layer of possible overrides
to the existing half-dozen layers, all of which are widely considered
features not bugs. So I see no merit in your argument.

Yup, you're dead right about that. Backup/restore of configurations
would become a real mess.
