You could make it work, but there would be a performance hit.

Now look at your cases where a filesystem doesn't work well:
 1/ Swap.  That is a non-issue.  After a crash, the contents of swap
    are irrelevant.  Without a crash, the races you refer to are
    irrelevant.

What about suspend to swap?

suspend is a "without a crash" case, I wouldn't want to restore from swap if the system failed to complete a clean shutdown.
