The docs on match types contains several aspects that are not implemented yet. In particular:

The "cannot possibly match rule". See Opaque types - selftype encoding #5300 (comment) for an interaction with opaque types.
Detection of overlapping patterns in general
Typing rules for match terms that allow a match term to have a match type without having to cast.
