No, 20mph zones and roads with 20mph limits are different legal concepts and are signed differently. A 20mph zone must have physical traffic calming. See TSRGD Schedule 10. That said, for OSM purposes, I agreed that there is no reason to add additional tags over and above maxspeed=. In practice all 20mph and 30mph limits are signed, and whether or not there are repeater signs makes no difference: the speed limits are discernible, verifiable facts. Going back to the Street Complete issue which prompted this thread, in https://github.com/westnordost/StreetComplete/issues/1037#issuecomment-385278398, suggestion #1 (the "quest" should be about speed limits, not the presence or absence of signs) is pretty clearly the way to go.
