Dante was not by default compatible with AES67 and neither was Ravenna, it was mildly inspired by and likely many of the engineers who work on Dante also work on the AES67 spec but AES67 is an industry specification much like any IEEE would be for EE.

AES67 also happens to be the audio backbone for SMPTE2110 which is why I predict we will see much greater penetration into the market.
