This is indeed what EVMS's new design does. It has user-space plugins that
understand a variety of on-disk-metadata formats. There are plugins for LVM
volumes, for MD RAID devices, for partitions, as well as others. The plugins
communicate with the MD driver to activate MD devices, and with the
device-mapper driver to activate other devices.
As for whether DM and MD kernel drivers should be merged: I imagine it could
be done, since DM already has support for easily adding new modules, but I
don't see any overwhelming reason to merge them right now. I'm sure it will
be discussed more when 2.7 comes out. For now they seem to work fine as
separate drivers doing what each specializes in. All the integration issues
that have been brought up can usually be dealt with in user-space.
