(We're getting into nits now.  OK.)

Only if REQUIRE-MATCH is non-nil.  And _that_
provides the feature I mentioned: only commands
are accepted as input.

With REQUIRE-MATCH = nil, RET does no completion:

(completing-read "Command?: " obarray 'commandp nil)

You can input `xxxxxxxxxxxxxxxxxxxx' if you like,
and it's accepted without being a command name.

What you emphasized is the result of a PREDICATE
arg of `commandp'.  But accepting only commands
has nothing to do with completing.  It has to do
with REQUIRE-MATCH.  Both are important here.
