The file system developers should not view this as being someone else's problem -- they can help.

Hmm... The only thing where filesystem can help is (4) - and it'll make spare files waaay too special IMNSO (today filesystem can add or remove holes to file at will). (1) is easily solveable elsewhere, (2) and (3) don't need any changes in filesystems...

<blockquote>[snapshotting] is easily solvable elsewhere</blockquote>

To the best of my knowledge, even if you do this at the LVM level, you
need file system support, in order to get a snapshot of a consistent
file system. Also, snapshotting at the file system will often be more
efficient (e.g., no need to back up blocks for new files). So I
believe that the file system is a better place for snapshotting than
LVM.
