As the README says:

YAML Language support uses JSON Schemas to understand the shape of a YAML file, including its value sets, defaults and descriptions. The schema support is shipped with JSON Schema Draft 7.

I would love to use features from a newer draft (specifically I'm looking at unevaluatedProperties though a lot of it is good). So shipping with the ability to use 2020-12 would be great! I tried looking around to see if there's any way to configure it to ship with a newer version or a reason why it would be, say, backwards incompatible and thus not implemented.

I tried searching the issues with the keyword jsonschema etc. so I hope this isn't a duplicate issue or answered somewhere obvious!
