I don't know if there is a policy, but I think return values should be
documented.

That includes what value it returns, IMHO.

What version of Emacs do you have?  In the current development
sources, the doc string of make-frame already says:

    Return a newly created frame displaying the current buffer.

So the return value, which is the frame object, is already documented.

As for the other two, the return nil, i.e. nothing, so I think it's
okay to say nothing about the (absent) return value.

That said,...
