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: https://commitfest.postgresql.org/42/3867/ If you're interested in that, getting additional reviews and comments on the work would be helpful in moving it forward.
