[Periodic Sync] Increased frequency when an app is installed and has active widgets

[aarongustafson]

In my proposal for PWA-driven Widgets, one of the ways we’re suggesting developers update their widgets is using Periodic Sync. With a frequency cap of 12 hours (at best), this approach is a non-starter to keep widgets up to date. I’d love to explore the possibility of increasing this frequency if

1. The PWA is installed and
2. The user has installed a widget with a defined update frequency.

It seems like these two requirements could naturally fit into the engagement-driven calculus for providing access to this feature. What do y’all think?
