I read it as it's the combination that is not allowed, but nesting
list itself works. So adding following to RFC might be enough:
"...
// This, however, is allowed:
[[$a, $b], [$c, $d]] = [[1, 2], [3, 4]];
// In a similar  fashion like
list(list($a, $b), list($c, $d)) = [[1, 2], [3, 4]];"

Anyway, nice and well written RFC, +1!
