I was wondering if we can clean up such stuff as soon as it is created in any RUN step? So there is no cruft in any layer.

As in this is a nice addition from security POV, but not from the size POV.

i would love to, but the files seem to come many differents RUN steps, and it would make the dockerfile quite hard to read. Although i will check - maybe it's only a small number of RUN that need the cleanup.
