Yes, it is.  

Real people count starting on 1, so they would tend to associate
modem1 with ttyS1 more easily than trying to remember that modem1
equals terminal 0.

Only if you use separate filenames.  

If the SCC A has only one entry named /dev/serial2 _OR_ /dev/lan
(depending on which one was selected by the user) and a terminal
which is always ttyS4, there can be no confusion.

I agree, but selecting user preferences could be done using an 
environment variable that the driver parses.
