No, because things go wrong too often and then it breaks for everyone. 
It's better now, but only because of the above reports and 3 
maintainers.

Also, it is not fatal. The schemas are checked against the DT 
meta-schema, but are used for validation if they pass just draft2019-09 
meta-schema. That allows new DT meta-schema checks to not start 
excluding previously used schema.
