Could you explain a bit why this is needed? AIUI it's just a latent
bug that discovered by this particular usecase, right? In other words,
not really a regression introduced by ioreq server.

refactoring are not  tracked.

The first one needs to be actively tracked if it's a regression.  I
already track the third one since it's a big feature.
