I think those two are really useful, for the reasons you mention.

For example, I have to copy config files to other machines quite often -
and possibly while the programs reading those files want to read them.  So
right now I do

  scp file remote:file.tmp
  ssh remote mv file.tmp file

which is more effort, and ugly.  If scp could do it in one go (copy to
tmp, if copy complete, move to final destination) it would save me
hassles, while keeping atomicity.

This is not something that would be useful for *me*, but I can see its
uses.
