Looking at the code, I'm going to guess that it's largely historical.
I'd guess that original core code was originally written for MS-DOS
(main.c?  RLY?), and once they got it working, they never went back to
fix things.  Even if it wasn't the most efficient way to do things, I
suspect most of the blind community didn't care once it was working
--- and they probably didn't have anyone who really understood the tty
line discpline layer, since it wasn't very well documented.
