One could argue this one, especially as there are people out there that don't
use scrollback. (Are you argueing that these should pay the price for
your opinion on features?) It is a feature for free, as it doesn't use
any memory. Additionally I believe it makes the scrolling faster with linux.
If you want a nice enviroment, just enter init 4 (or 6,
depending upon the age of your inittab :) ), and enjoy X.

And much more costly in terms of memory:
PID TTY MAJFLT MINFLT TRS DRS SIZE SWAP RSS SHRD LIB DT COMMAND
7122 p5 366 105 108 1736 1844 0 1844 1204 0 104 xterm -sl 100
7147 p5 351 919 108 3364 3472 0 3472 1204 0 511 xterm -sl 10000

In both cases I just scrolled past 10000 lines of ls -l /usr/bin output.

And while I've enough memory to allow myself a 1000 line scrollback as
default on my xterm, I wouldn't do this if the buffer for the 1000 lines
would have to be kernel memory. And I believe that there are many users that
don't want scroll back, but instead favour some 50KB or 100KB of more memory.
(a good friend of mine has constantly problems with memory on some Thinkpad!)
