I have a proposal for a category name that starts with a C0 control character.
 That should be no problem, right?

Not quite with the syntax you spitballed, but conceptually, it seems to.

$ echo '.warn -missing' | htroff > /dev/null
$ echo '.warn all-missing' | htroff > /dev/null
troff: unknown warning category all-missing; line 1, file <standard input>
$ echo '.warn all -missing' | htroff > /dev/null

And lest one is concerned it's merely ignoring the second argument:

$ echo '.warn all -hissing' | htroff > /dev/null
troff: unknown warning category hissing; line 1, file <standard input>

Agreed.
