Interesting. I'm curious about how people envision the flow of
information with regards to personalization. Our ultimate goal is
reader control over some aspects of presentation. But how can the
reader express their requirements, and how can content authors respond
to those requirements? The user stylesheet was the original solution,
but that hasn't exactly been a huge success. There seems to be some
interest in setting user preferences at the operating system level,
which content authors can discover through media features—the
prefers-reduced-motion media query is an example.

Would the role of a web application manifest in this scenario be
purely to provide metadata—to advertise to the user agent (and thus
the user) that this web content does contain affordances for a defined
list of user preferences? That sounds fine to me, but I do want to
avoid having actual rendering information in some new format.
