I also thought this should not be something unique to us. So I asked
in our internal mailing list, I heard nothing back.

This is a good point. I asked there (nothing since 1/24):

When we were working on our device side, we had to change some QEMU
code and later noticed that HAXM also requires some fixes (we had
meetings with Intel). I suppose QEMU does not have this feature yet.

Could you please tell if we can proceed with upstreaming as is?
