It's not the next big thing, but it is very interesting feature
enabling higher performance as reading/writing to the module (and
subsequently to the file on the host) does not require a VMEXIT.
It can be used to access host files directly bypassing page cache
whilst doing so.
Looks good. Main thing from the libguestfs point of view is it
supports setting the shared access to 'private', so we can use it as a
way to accelerate the appliance root disk, which might also be of
interest to other libvirt users.
