TL; DR
Android 17 will add a 3rd companion role profile called medical profile. Apps using this profile get default access to notifications, exact alarms, bluetooth. Apps using this role will be prioritized over standard battery and memory savings of android – reduce chances of being killed.
Hopefully google learned from the nightmare that PWA were, specifically with websites taking advantage of the features to spam you with shit if you make the tiniest mistake when giving them permissions.
