I've been known to say that with DANE TLSA, explicit revocation is
superseded by publishing an updated TLSA record.  Don't know whether
that was ever in the context the revocation discussion in question.

Of course that only applies to situations in which DANE is always
used.  DANE is of no help when the verifier is using "traditional"
PKI.
