Valve appear to have some pretty ambitious future plans for Steam, as we've seen recently a leak (and not for the first time) that Valve has plans for ARM64 and Android support on Linux.
This would make a lot of sense if valve plan on releasing new iteration of their handheld.
It makes more sense that for the immediate future this is for ARM Chromebooks. Steam for Chromebooks currently only works with x86 CPUs. For the longer term, all kinds of options open up because of this, of course.
