If people care to take advantage of your expertise, I hope they can
provide the filesystems that have failed as examples.  "overlay is
fragile" is about the level of FUD, AFAICS.  Nothing better has been
proposed.  No broken filesystems have been made available.  I don't
doubt the "some sticks 'broke' when yanked out before fs's were
sync'ed" reports in and of themselves, but when this meme continues it
makes potential contributors / onlookers think there is some obvious /
neglected problem.
