The spec already has the "cookies" parameter clear TLS Channel ID and bound
tokens.

Are TLS session tickets more like that or more like cache? Even if they
aren't really auth-like things would it be less confusing to lump all the
TLS-tracking things together?

Do we expect users of Clear-site-data to pick and choose types, or are they
just going to use "*" in practice?
