a hint in Kconfig makes IMHO sense. Do you want to send a patch?
A warning is too much since on some tiny embedded system with NOR flash mtdblock is still
a good choice.
ubiblock is mostly useful for NAND flash.

a long time ago mount didn't accept character devices, so you had to pass mtdblockX to mount
JFFS2.
This limitation is gone.

Thanks,
