@chucker Given that WBM already has a date-specification syntax, with options for wildcards and (I think) date-ranging, this would be a sensible proposal.
I've been thinking for a bit now that URLs and especially domain names should have a date-specification, and that notions such as transfers, especially of personal domains, should be ... far less viable than they are now.
(Naming things is a Hard Problem, especially when it intersects with timey-wimey stuff.)
