Sounds good to me. While I personally don't think such a check is
necessary in this case, I also have nothing against it if you find it
important.

It just needs to be possible to disable that check itself, too. I
certainly wouldn't want to be bothered by it, even if the rescan should
take longer than whatever threshold you decide on. So if you put up a
dialog to inform the user, the dialog should ideally have a "Don't show
again" option.
