I see no resistance. I see lack of man-power.  Any extension needs:
1- guest driver support
2- qemu support
3- spec documentation

Current scheme has (1) by now, a beginning of (3) and a rudimentary
prototype of (2).

For your proposed extension, you can either do some of this work, or do
some testing to demonstrate problems and motivate others. So far
emailing list about theoretical issues did not seem to motivate anyone.
