[CQ-Contest] Why?

Why is the RTTY Roundup so named?

If I read the rules, all digital modes should have equal standing, i.e., 
RTTY (200 Hz or so wide), PSK-31 (30 Hz), BPSK-63 (about 70 Hz), etc.

Should it not be called the Digital Modes Roundup?

And, with BPSK being about 67% better than 45 baud RTTY in spectrum 
efficiency, why does the ARRL promote RTTY rather than a more efficient 
mode such as BPSK-63?

Yes, I know I've heard that PSK-31 operating is like watching paint dry, 
but folks tell me that BPSK-63 is as rapid as 45 baud baudot. So, why 
does the contesting community stick with an early 1900's mode, rather 
than adopting a more spectrum efficient mode?

If it's because of habit, why aren't we all using sp*rk gap transmitters 
and coherer detectors?

Just a few questions which came to mind as I was reading the rules for 
the RTTY roundup.
