I don’t take comments about unrelated things.  ;-)

As someone who writes gexps and manipulates “file-like objects”, it
doesn’t matter whether a thing lowers to a derivation or to a plain
store item.  What matters is that you can insert it in a gexp and it’ll
do the right thing.  That’s why the docstrings don’t insist on that
difference.

Hope it makes sense!
