In terms of the Priority of Constituencies principle, it'd seem to
me that between #2 and #3, #2 will -- in the long term --
ultimately have lower costs and difficulties for authors, though
higher costs and difficulties for implementors in the short term.

I would think a big red flag ought to go up for any proposed
solution that we know will lead to introducing complicated and
elaborate hacks into new content. For one thing, we know from
experience that due to cargo-cult copy-and-paste authoring, such
hacks have a tendency to live on in content for years after the
need for them in widely used UAs has disappeared.
