That's how it works currently.  But we're talking about making changes.

Right.  That's why I suggested to use C-x C-w for this particular case.
(but rename-file (c|sh)ould still be changed accordingly).

Nope, it ignores prefix args and the `along-with-file` argument only
tells it that *something else* has moved the file.

If it's only done when used interactively, it should be safe, yes.

Hence C-x C-w (aka `write-file`).
