Aha, nice, so it looks like ubifs is a step back here. 'clean marker' is a good idea... empty pages have plenty of space.If UBI (not UBIFS) faces an empty block, it also re-erases it.Unfortunately, that's not the case, though UBI can easily be patched to do that (see below).
Sorry for the noise, I was wrong, UBI already re-erases empty blocks [1]. [1]http://elixir.free-electrons.com/linux/latest/source/drivers/mtd/ubi/attach.c#L983
