I guess you mean adding such warnings to zshparam(1)?  In which case,
perhaps adding them to bin_typeset() would be more effective?  As in:

% export HISTORY=foo
zsh:1: warning: $HISTORY should not be exported; use 'typeset HISTORY=foo' instead

(and if someone actually needs to export $HISTORY for whatever reason,
we can make -h suppress the warning)
