Using unique URIs to define resources is a common behavior to many sites
and is widely recommended in blogs/books/etc. It seems worth creating a
standard way to implement this recommendation that is far simpler than a
service worker.

Shift-reload is a tool we provide our users to get around this class of

This draft does not suggest altering the behavior of shift-reload.
Shift-reload should continue to be an absolute refresh of the site -- for
example I believe in Chrome shift-reload even ignores service workers. In
future drafts it may be worth being more clear about this behavior.
