There's ongoing work to provide a way to have a global maximum limit
which doesn't involve entirely reworking how work_mem works today. The
commitfest entry for that work is here:

If you're interested in that, getting additional reviews and comments on
the work would be helpful in moving it forward.

Thanks,
