Why should this raise an OperationError. For copy() to be idempotent, the destination file existing, should just be a noop right? Alternatively, you could compare hashes to see if the src file has changed.

Indeed a noop would be a better fit here, although I still feel that an error should be raised in case dest_file_path already exists and is different from src. So maybe something like this?
if dest_file_exists and not overwrite:
if _file_equal(src, dest_file_path):
host.noop(f"{dest_file_path} already exists")
else:
raise OperationError(f"{dest_file_path} already exists and is different than src")Or maybe there's a better way to handle that case?
Also, in the snippet I use the _file_equal function, but that seems to be intended for local-remote hash comparisons.
Are you aware of any functions that might better fit this use case? Should I just create a new internal function based on this one for remote-remote hash comparison (what could be a nice name for it?)?
Adds copy operation suggested in #1121. Any and all feedback is welcome!
