It's a horrible, ugly hack: please provide proof that you've
unsuccessfully petitioned the broken vendors before trying to
introduce it.

I agree with Alexey: this is exactly what we should be avoiding.  If
you want to generate a RST in response to a locally-destined packet,
it's easy for most cases.  There's even an example of doing exactly
this in libfw.
