as long as your phone have GMS preinstalled and listed under Google certification. this will affect you. So, Chinese phone without GMS is fine.

5. I think for noobs it will be better they buy the Chinese phone such as Huawei that does not certified by Google and emulated it with gbox for GMS support. Then they still they got their favourite apps going even banking apps as well. https://storage.googleapis.com/play_public/supported_devices.html

if this policy is implemented. the easiest thing for noobs will be get a Chinese phone without certification from Google https://storage.googleapis.com/play_public/supported_devices.html like huawei (you can get a GMS support with emulator like Gbox)
