No warning is issued when a request has extraneous arguments, e.g. ‘.ce 3 1
4 1 5’.  A warning should be added and included in the ‘all’ grouping of
warnings.  Experience from deploying that warning will allow a future choice
on whether extraneous arguments should be upgraded to an error, e.g. there's
no widespread historical habit of extra arguments being provided knowing that
they'll be ignored.

Conversation causing this bug report occurred on the groff mailing list in
2021-11 under the subject ‘Two trivial questions’.
