oddly enough, Linux console uses modifiers less than xterm.

XFree86 xterm keyboard handling normally (the default resource settings),
does use modifiers (but your posting implied that you're not seeing that
behavior).

as for why (vt102 - or vt220) because it simplifies using systems that
people occasionally find useful.  A complete redesign won't solve that
problem.

it seems to depend on the system - I was quoting from Solaris' xterm manpage

xterm control sequences is not a manpage - there's an nroff-formatted copy off
my webpage (but it looks nicer in postscript).

like all jargon - it's simple if you're familiar with it.
(and once familiar, one forgets that it's jargon).
