Google+ Login Scope

Hi there,

I noticed that when authorizing, the plugin asks for language and age range.

I found how to disable it by editing the code and altering the scope to:
$googleClient->setScopes(array(‘https://www.googleapis.com/auth/userinfo.email’));

However, I do not know:

Is it necessary for the functionality of the plugin?

Can it be disabled via an option?

Thanks in advance
