This is more standard Unix fare. You look at apt's output and see how
you filter it with grep. Apt's man page can't cover grep (and all of
the other filters available to you).

See above. The apt man page would become unwieldy that way. Would you
include apt in the grep man page too?
Composition of commands is at the heart of Unix[1]. That's why the
commands are usually built to input/output text, to enable you to
stick them together. A big Lego set, if you want.
