We have used a similar setup for sharing /usr/bin, but it is quite restrictive
in terms of updates.

OK.

If there's a case where it's needed, and can be used safely, then I expect
we'd take a patch for it.

It will never, ever, be safe to mount a non-cluster filesystem as anything
other than "single writer, no readers", or "multiple readers, no writers".
Perhaps the best you could do without using network would be to shut down the
domUs, mount the module filesytem in dom0, copy in the new modules, then
unmount in dom0 and restart the domUs.
I realise it's a bit clunky doing things this way, but anything else is liable
to require more complexity than you want to implement in the storage
configuration :-(
Cheers,
