So far I have not had a pleasant upstream experience when submitting
this particular patch to upstream.

Of course everybody is welcome. However, NACK without technical
justification is very bad for upstream development. I can't imagine
what a new hacker would think after going through what I have gone
through for this patch. He/she will likely quit contributing upstream.
This is not the kind of welcome we want.

Nhat needs to be able to technically justify his NACK as a maintainer.
Sorry there is no other way to sugar coat it.
