Sure. There are many cases where evaluation in buffer helps to insert
text into buffer. I am writing consulting related emails since
decades. Sometimes real time information has to be fetched,
recalculated and English or other language sentences constructed in
the buffer and expressions may not be repetitive or already defined as
functions. That is where inserting into buffer helps.

It also helps when analyzing as visibility in the buffer is better
then short message display in the minibuffer.
