I grepped the Emacs tree.  There's only ten instances of

(insert (with-temp-buffer ...))

But there's over 200 instances of

(with-temp-buffer ... (buffer-string))

where some of them basically eventually translate to inserting that into
the current buffer -- some of which do the `insert-into-buffer' contortion
themselves.
