That puts all the information in the declaration line with parallel syntax and
semantics, and would even allow both by-val and by-ref usage for both lexical
and global values. The following would then be exactly equivalent
functionality-wise:
function foo() global (&$a) {
// ...
}
function foo() {
global $a;
// ...
}
Is that too crazy an idea?

I think allowing globals/lexicals to be passed by value doesn't make
much sense, you could just use a regular parameter for that. And that
would bring another inconsistency to PHP, and would mean that PHP is
discouraging the use of $_GLOBALS, that was created to discourage to use
of 'global $var'.
