regarding the reasoning behind the need to have this information added to the statistics, I do think it makes more sense to track Push_enable_gateway than if the gateway was changed or not.. because usually people will either use our apps with our gateway or change do not use our gateway with their own mobile apps.

and since we've been adding too much information to the statistics recently, I'd like to encourage some thinking on how to improve it.. for example, if we're tracking many different push related settings, maybe we can use a binary value? like:

we want to track 3 different settings, each one of them receives receives a bit:

1 1 1
| | |
| | +- push enabled = 0b1 = 
| +--- push gateway enabled = 0b10 = 2
+----- push gateway changed = 0b100 = 4

this way we could have a single value sent to the statistics using bitwise operators, like this:

const pushEnabled = settings.get('Push_enable') ? 1 : 0;
const pushGatewayEnabled = settings.get('Push_enable_gateway') ? 2 : 0;
const gatewayChanged = hasGatewayChanged() ? 4 : 0;

statistics.push = pushEnabled | pushGatewayEnabled | gatewayChanged;

just an idea I think we should consider =)
