For the record, ksh used to have a number of builtin aliases,
but they were causing all sort of problems including breaking
POSIX compliance as things like

suspend() { ...; }

for instance would fail (as suspend used to be defined as a
suspend='kill -s STOP $$' (yes, with the missing quotes around
$$ (!), see https://github.com/att/ast/issues/10)

So they were eventually changed to being separate builtins (on
my request IIRC, though I can't find the bug report any
longer).

TLDR, I think zsh should avoid having builtin aliases.
