php_support2 is same as php_support but passes queries only to local PHP.

Here you have it. As I said nothing special here.

Why? I know that if is in rewrite module in docs but can't we use it in other places?

Do you suggest to use nested location rather than if() in that case? But still (and dont yell) - it worked before.
