Oh, ok. Sorry about that. Generally when I say "we" I include as large
a part of the community as applicable.

No problem with that (and in fact I agree, as I'd prefer a speedy
merge and doing the work on the QEMU master branch); however, we need
to reach an agreement on that and everybody (including Daniel) needs
to explain the reason for their position.

Daniel's proposed criteria for merging include:
- CI integration
- CI passing for all supported targets (thus lowering the MSRV to 1.63.0)
- plus any the code changes that were or will be requested during review

That seems to be a pretty high amount of work, and until it's done
everyone else is unable to contribute, not even in directions
orthogonal to the above (cross compilation support, less unsafe code,
porting more devices). So something has to give: either we decide for
an early merge, where the code is marked as experimental and disabled
by default. Personally I think it's fine, the contingency plan is
simply to "git rm -rf rust/". Or we can keep the above stringent
requirements for merging, but then I don't see it as a one-person job.

If I can say so, developing on a branch would also be a useful warm-up
for you in the maintainer role, if we expect that there will be
significant community contributions to Rust.
