One area of push back I have here is that the Discourse Hub app is still a tiny bit superior to the PWA
- Multiple sites in one
- Push notifications for all our hosted customers
- No need to log in a second time due to auth handover protocol
- Share link in footer instead of just back/forward
- Easier to install (arguably)
That said … this is great progress, for sure! It is super usable 
This kind of solidifies that the experiment with the loud nagging and teaching should be in a theme component (with an optional mode for teach about hub vs teach about pwa). Also makes me wonder if we can teach Hub just to lean on web push notifications as well for self hosted…
