That's really interesting, I hadn't realised that Ravenna was around first. The underlying transport and timing mechanisms in Ravenna align well with AES67. I suppose it's not surprising as AES67 is really more of a specification of interoperability than a ground-up spec in its own right. All the Ravenna-enabled devices I've come across offer a very good level of AES67 compliance.
As for SMPTE 2110, I'm not sure that a separate control network is a hard-and-fast requirement. (I think I've read all of 2110 now but only once, so I'm happy to be corrected!) It certainly is the case though that larger installations benefit from a separate control LAN, and that broadcast oriented kit tends to offer a separate control ethernet interface to facilitate this. A lot of the really big installs are taking their lead, from a network topology perspective, from datacentre design where out-of-band management LANs are assumed.
