Sound like microg is to GooglePlayServices what wine is to windows.
Great effort! As of today, we don't really have any truly functional 100% FLOSS mobile ecosystem. To make things worse, even if we have, people have moved very strongly to proprietary IM networks and alike, regrettably.
Most things in tech come in waves (thin clients, h/w vs s/w speeds) and this is nothing FLOSS hasn't overcome before. A few more stories about abuses with NSA/Apple/FB/Google/whatever and OSS will be back on power user's primary devices and not just servers.
That's not to say it won't take effort. No need to get complacent :).
