I don't think it's going to happen in the short term. 70% of our users are on devices outside of the better featured google nexus, samsung s, lge g, motorola moto, etc series phones. Even though our user base leans towards early adopters, less than 2% are on the nexus 5 (nexus 6 is too small to show up in the stats). google posts their stats on os adoption here: https://developer.android.com/about/dashboards/index.html. 30% of users are on 4.1 and above. Phones running lower than 4.1 are not going to benefit from the smarter GC. If you're supporting international users, lower end phones will likely be a bigger percentage of your userbase.
