That doesn't excuse failing to design the code properly.

Actually there is a whole academic world out there, lots of papers and
research OS code including Linux based bits.

So you want to shove crap in the kernel with a broken ABI someone (no
doubt not you) will have to keep maintained forever ?

I'm not suggesting it's delayed - I'm suggesting its designed properly in
the first place.

We know the kind of use cases that are coming. Designing in complete
ignorance of them is just stupidity.

Atul wants to put something in staging, and grow it from there. That's
not delaying it, but trying to get it done right.
