stream.el is at its core just an implementation of lazy-cons cells, so
not letting stream0 get access to the result would mean changing the
core implementation (I'm not necessarily against it).
If we accept that `seq-elt', and other positional functions of seq.el
should not work on streams, then I could rewrite stream.el to make it a
positioned stream where previous elements are discarded after each
element generation. However the list of supported functions from seq.el
API would be significantly reduced.

No, it doesn't.
