Currently, I don’t think that it’s possible to get an error when
copying the content of a file from another revision into your
working tree if said file has uncommitted changes.
Yes, "git restore <from-where> <pathspec>" is like "I made a mess in
the paths <pathspec> in the working tree and I want to start from a
known state, so please take the contents for these paths from
<from-where> and overwrite the garbage I have in the working tree".
It would be a grave regression to stop overwriting by default, as it
misses the entire point of the command.
The same applies to "git checkout <from-where> -- <pathspec>".
