Play-games-plugin-for-unity: [Discussion] Are there actually any problem to use playservice in other platform aside from android?

[Thaina]

While android natively support play service by default, play service still have REST api to be called from any platform anyway. So are there really a problem at all to just use REST api on other platform such as IOS, desktop and webgl ? Is it any limitation or prohibition from google?

If not I think I would like to try implement the REST client into this plugin, will there be any problem?

The problem will be if user haven't game profile and it need to be created. As currently it can be done only on Android.
