Pretty much because other ISO standards specify the meaning of that set,
and Unicode/ISO 10646 very much didn't want to go there. I say "meaning",
but there are actually multiple possible meanings, though most of them are
fairly consistent.

Note that the presence of NEL in the C1 area (U+0080 to U+009F) reflects
an earlier attempt to do the same thing that generated LS. Some ISO
committee recognized that LF was being overloaded to mean "move to the
next line" and "go back to the beginning, then move to the next line"
and introduced the characters U+0084 (IND) and U+0085 (NEL) to
disambiguate, presumably in hopes that LF would eventually be abandoned
in favor of IND and NEL as appropriate.
No such luck, Doc. <chomp/><chomp/>
