I want to know if someone do sg. like this, and I want to talk with.
If it clears itself, the problem just "disappears", and stronger the beleif
that the network is unreliable.
Otherwise: If you plan well, you will know at the planning state, what
ports will be backbone ports, and you allow pdu's there, and you will know
what ports will be access ports, and you allow spanning-tree portfast on
them, but if you don't want to mess up things, you should also allow

Thats nice in theory. The only issue is that, I never seen this nice

It's true in a case where you have no choice about incorporating a
device which doesn't complain standards. But as I said: If a networking
device doesn't complain so obvious standard, like autonegoiation, it will
mess up other things too.
I glanced at your other mail, and I saw, that you wrote about cisco-sun
difficulties. I think thats a good example: If you have no other working
solution, It can be the right way. But I have to repeat myself: Only if you
have proper documentation about those hardcodings/hacks/whatever.
