From what I read you basically answered all technical comments like in:

The dbus API is like it is for a very good reason, everyone is using it
and everyone agrees. Capabilities are used in userspace for good reason
and so on.

But I see, here, not everyone does.

Most of your answers didn´t seem to address the concerns raised of having
this in the *kernel*. Especially the security concerns.

Thats what I meant with "And yes, I think its good not to force just about
any userspace into the kernel". I think arguing with this is how userspace
does it pattern, even if it truly is for a very good reason, is not
sufficient as argument for having it in the kernel.

I am just looking at the argumentative pattern here. If other kernel
developers complain about how hard it is to review and wrap their mind
around the kdbus patches… I am scared at just trying to understand the
patches. So no technical complaints from me. I did not nack it nor do I
see myself in the position to nack it.

So feel free to do with my argument what you like. I just tried to
understand why the communication in here works in circles as it does and I
think will continue to work like that as long as its the userspace does it
that way argument or this is optional argument only. For the discussion to
go anywhere its important to acknowledge each other.
