guessing (and commenting on the standard terminfo capabilities rather
than extensions):

a) it wasn't used in vi
b) "back then", ANSI terminals weren't the dominant strain
c) this feature came kind of late anyway (appearing in DEC terminals ~1994)
d) with most screen updates going top-to-bottom, CPL didn't seem useful.

Adding it as an extension capability doesn't cost much...
