I personally think it's fine to have multiple proposals on the table.
For example, current Zhu Lingshan's patch is clearly incomplete without
memory change tracking.
Why shouldn't he post a patchset demonstrating
how that is supposed to work in his view?
I am personally interested in seeing how is that
supposed to work   - his latest proposal relies on migrating by
trapping memory accesses but DMA can't be trapped like this generally.

In the end we want something addressing all use cases though
and integrating reasonably well with existing ecosystem.
