So, many of these cases were what the original HTMLNotification API was
supposed to address. This was eventually shot down for a number of (good)
reasons: too much complexity on the implementation side, and more
importantly, the fact that these more complex notifications aren't
compatible with various platform notification frameworks and so this would
be a source of platform/UA incompatibility. It's not clear to me that
re-adding support for these use cases one at a time as distinct
notification types is really a good path forward, or that it's necessarily
"low-hanging fruit" unless we have a good idea for how to deal with the
platform-compatibility issue.

above, then this needs to be part of that proposal - for example, I'm not
sure how valuable having something like a "Date/Event" notification would
be without a "Snooze" button.
