I used mdoc(7), conventions section, first paragraph.

I considered that, and if option and non-option were mutually
exclusive I would have written that. The problem is that

    $ mktemp -t foo bar

is valid and will create files "$TMPDIR/foo.<8-digits>"
and "./bar".

Personally, I am fine with either of the three solutions.
