Maybe there are very few of commands that issue these messages, in
which case a case by case approach is not that bad.

We have infrastructure for delaying messages, see "Delayed Warnings"
in the ELisp manual.  Using something like this could solve this issue
without inordinately affecting more important functionality.

I think this is pretty clear: we want to delay when a shell script is
visited via the client.

In that case, we visit the file in an existing frame.  By contrast,
the client needs to create a frame, and if it does that before
visiting the file, it will momentarily show some other buffer in that
frame.
