[csswg-drafts] [css-cascade] What is the migration path for custom origins? (#4985)

mirisuzanne has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-cascade] What is the migration path for custom origins? ==
This is in relation to #4470 custom-origin proposal. To quote @frivoal in the transcript from our original discussion:

> florian: One thing I'm a little concerned is how we figure out the syntax to have a migration path toward this from legacy CSS.
> florian: In particular, a syntax ignorable by old browsers is bad because the cascade will be all mushed up; but making it hide rules from old browsers means they'll just miss a lot of code.
> florian: Writing everything twice is bad, but not having an upgrade path is bad.
