Notifications are a particularly hard case for the principle of requesting
permissions in response to user action, because the whole point of
notifications is that they happen when the user isn't giving the application
attention :-).

Another possible approach would be to have the default be for notifications
to show up in browser UI associated with the page --- e.g., highlight the
tab title and show the notification(s) at the top of the page if you switch
to the tab --- and in that notification-showing UI, offer a "show on
desktop" button which lets the notifications for that application migrate to
the desktop --- effectively a permission grant.

Of course, asking each of these while using the application would also be

I think we have to consider specific cases. For Skype, it depends on whether
all those permissions are really needed, and why... It might not be that
hard to figure out how to make on-demand permission grants intelligible. We
owe it to users to try.
