Within a short time you will then discover that the upper limit is too low
and there are problems again. To make it clear, two months ago I needed to
write support in a mailer setup program for serial ports upto 4mbit
baudrate. You mention 128 kb over ISDN, this is without datacompression, do
we need a new baudrate field if we start transfering data at aprox. 400 kb
with compression over ISDN. In my optinion we only need capability flags.
Lets stop the baudrate bidding at the point were we are now. 

Youre right with this point, the baudrate field belongs to ancient modems
that needed it.

Gtx,
  Michiel
