Yes, please. This is one of the major reasons why I stopped using
RAIDframe on my server.

But just splitting the flag won't help. IIUC RAIDframe only sets the
parity clean bit if the the last user of the device closes it. It will
need to use a scheme which dynamically marks parts of the disks as
clean and unclean.
