How? If you provide the ability to determine alternative selection based
on package priority (Important/Standard/Optional/Extra), why do you need
alternative priorities (numerical, set in in package maintainer scripts,
locally overridable)?

(The fact that we are using the word "priority" to mean two different
things is perhaps confusing, which is why I've been trying to
distinguish "package priority" and "alternative priority".)

We *already* have an override: it's called 'update-alternative'. Why do
we need two?

Sigh. No, it's "most of the time, for most people, our current system
defaults in an appropriate manner, and for those rare occasions when it
doesn't, we have the tool to override."

It makes it harder for maintainers, and it makes it harder for users,
because there would then be two completely different ways of overriding
default alternative priorities. Which would be dominant? Which is
preferred? How do you test all the interactions?

We have a straightforward system that provides a) reasonable default
behaviour, and b) a standard way to override the default. I don't see
the point in complicating that to provide a solution to a "problem"
that has been invented just for this thread, and has *no* outstanding
wishlist bug reports.
