I know DT and bindings are a bit specific but they are still in the
kernel sources and right now in MAINTAINERS, under the MTD subsystem
entry there is:
F:      Documentation/devicetree/bindings/mtd/

What I am saying is that this list is a duplicate and people will
simply forget about it so it won't be updated naturally.
