no, I only refuse to listen to you.

You are neither maintainer for any subsystem that is involved nor have
you contributed technical arguments pro/con and it appears to me that
you refuse to listen to my argumentation.

Which promises did I not keep? Please be specific, instead of insulting.

I bring up this alternative again, since I get the impression that most readers
are simply not aware of *both* alternative proposals.

Please provide better arguments and don’t spread FUD.

Please have a look into our RFC implementation and study it carefully
to learn why it is the better (IMHO more flexible, easier to maintain, more
modular) approach. Even if you don’t like phandles.
