It is actually what I had in mind, but I am concerned about several
possible caveats:

1. Introducing a query where there was none previously may break
   noninteractive Emacs and existing code that makes an assumption about
   `find-file' not querying user in most cases.

2. autosave data is just one of several cases when `after-find-file'
   uses `sit-for':
   - "File exists, but cannot be read"
   - "Symbolic link that points to nonexistent file"
   - "%s has auto save data; consider \\`M-x recover-this-file'"
   - "File not found and directory write-protected"
   - "Use M-x make-directory RET RET to create the directory and its parents"
   It is not clear if all of these cases should ask user immediately and
   wait for an answer or just some of them. And if just some of them,
   whether to leave the `sit-for' delay after displaying message or not.

We are in agreement here. I also do not think that set-multi-message
should be used everywhere.

However, I do think that using `sit-for' to attract attention is not a
good idea and such approach should be replaced either with explicit user
prompt or, when the message is not as important, with something that
does not block Emacs (like my proposal or something else we can come up
with).
