Uuuuugh the last thing I want is notifications becoming like email, where it's so spammy and impossible to deal with that automated tools have to start categorizing spam and affecting message visibility, and then important messages start to get lost in the shuffle.
That seems like the unfortunate but inevitable outcome of any unregulated channel between devs and users once it's passed a certain popularity threshold. Time to move on from push notifications to whatever the next thing is to enjoy a decent signal:noise ratio there for the 2-3 years before it catches on with the masses.
