Here's my opportunity to ask a question I've had for a while: do you
have a way to filter out dtbs that are known to be bad actors (ie have
many many warnings)? Maybe a list of platforms you talk about below
that aim at zero warnings?

Another way to ask this: what would be a good default DT_SCHEMA_FILES
value? Not filtering leads to way too many errors.
