Why would I need such a thing, I don't need any changes to /dev.
Even if I pop in a usb-disk, I just mount it.
Udev do not in the slightest solve any of my needs.
So why are you telling me that I must have it, yes, software 
dependancies are a problem. I'm interested in answers that tells me how 
to solve that without calling in extra software and deamons.

You can try gpm to do that.
Udev do not do any way of serial mouce detection, never has.

I'm not a passive consumer in this as you seem to believe.
If I decide I will resurrect thoose x11 drivers, I will do so.

Yea, it does, simply because udev doesn't touch any serial mouse,
you have to fill in your own xorg.conf section for that or use gpm 
in a console. Udev just cares about the serial port, not what is
attached to that port

Bluetooth adapters mostly comes in as a usb device, thought there might 
be thoose with an i2c connection for the embedded market.
I don't know about thunderbolt.
esata as well as sata just works well without udev.

And I do not need a deamon to handle that.

Well, "if at all", so you agree with me that udev isn't for me.
What I'm looking for is alternatives.

So, udev isn't for me, what do you complain about.
I don't say to others to not use udev, I don't care about that.

I ask, how can I make my case work without udev, because honsestly,
it doesn't bring me shit and I'm not interesed in using software that 
doesn't do anything for me. The problem of device nodes and permission 
is already solved, I don't need pop-ups, I don't want automounting.
Serial ports have been working for the last 70 years or more.
So stop this, I never asked about udev or how to make that work.
You are answering the wrong question.
