The value of screen is numeric, and the standard includes a statement about what value is used when screen has not been specified. (The statement ends with the words "of these shall be used" that are quoted in the desired action.)

Yes, it does say what default should be used, but it does not say that this is the actual default. But all looked-at implementations do not set it by default.

So as POSIX specifies whether or not a variable is set by default it should definitely do this for *screen*, too.
(Reminder that for mailx "set noXY" equals "unset XY", "set noscreen" is thus identically to specify the variable is not set. So "shall be noscreen" means the variable is not set by default, and the default algorithm shall kick in. Which is what implementations do.)

Okay, I see your point now, and I notice that crt (which is also numeric) has "The default shall be nocrt". So I'm fine with adding an equivalent statement for screen.
