Yes, we (Netflix) have the Arista 7500R and 7280R widely deployed as edge routers. We're a few months away from shutting down the few remaining MXs and ASRs in our CDN.
There was a thread from about a year ago that you might check out: https://mailman.nanog.org/pipermail/nanog/2016-April/085472.html Since then, route table growth hasn't changed appreciably. Also, Arista has added some features (notably route-map subroutine support and default-deny) that improve BGP policy functionality. If your use case allows you to use a default for those routes not heard via your direct peers, there are options to increase the functional scale (and thus to stretch the lifespan beyond ~4 years). In addition to filtering, there's support for selective route download, which will allow you to keep a full RIB with a more limited FIB.
