It's disabled because it always has been, and therefore enabling it might
break longstanding usage.

It has always been disabled because zsh originated as a way to bring
Bourne shell syntax to students who had been introduced to BSD Unix
via [t]csh, and csh does not have interactive comments.  A lot of the
default behaviors and interactive design of zsh derive from Paul Falstad
(the original author) making subjective judgements about what were the
best features of csh and sh, rather than about what features were the
most common in other sh clones.
