I don't know what this means for phones that haven't been manufactured yet and whether Huawei will pre-load them with the G Apps.
The big question now is for how long "Google Play and the security protections from Google Play Protect will continue to function on existing Huawei devices." We'll probably find out more during the week.
A) all Huawei phones (old or currently being sold) with Google services will keep access to the services, even in the long term?
B) the only effect fo the ban on current Huawei phones (old or currently being sold) will be that updates will be stopped?
A is good news, but B is catastrophic. This means that the effects of this ban will be to put Huawei customers at risk.
One thing is to prevent customers to access a given service. Another thing completely different is to allow access to a service, and then let those same customers down regarding security updates.
I hope that at least security updates will be allowed.
