So, in order to merge something that is not accepted upstream yet, is it an 
accepted way to encourage distros to use it nonetheless, to get it upstream 
then anyway as in "as, look, now this and this distro uses it"?

I think you didn´t mean it that way, as you state proper technical review as 
a requirement.

Can you clarify?


Still as far as I got it, Andy raised technical concerns which Greg 
outrightly rejected as invalid without any further explaination. That does 
not seem like technical concerns have been properly addressed to me.
