Absolutely. I agree with this entirely. But these are mechanisms to
express in the application layer that the representation that the UA
requests of the resource differs from those the UA claims to accept.
Where the browser is able to express what it wants, we should listen
to it. We should not default to expressing in the application layer
what is ignored in the protocol layer.

I agree. The operative word here is "alternative" -- these are ways to
address a resource other than the canonical URI + request headers, and
one ought to strive to remove these where practical.
