It seems that automatic scaling was added to create-image in february
2016, so the bug may have been there since than.

How about fixing the bug and documentation on emacs-26 (patches 1 and 2)
and making the behaviour change (patch 3) on master?  I think the bug
fix (patch 1) is obviously right and not likely to cause problems.
OTOH, without it, once I had invoked an image transform I could not use
image-mode for any new images any more in that same Emacs session.

Thanks, benny
