You may not like the current implementation, but that is no reason to 
deny
this documentation of the current state.

Personally I don't get this preference for aliases. It is a one way 
mapping
in the wrong direction if you ask me. If e.g. you have serial0 pointing 
to
a 16550 it will give /dev/ttyS0. This prevents you to create 
/dev/ttyUL0,
because serial0 is already taken. Note that ttySx and ttyULx are in
different namespaces. It would only make sense if ttyULx was an illegal
name for a UART.
