Yes, that is right. I believe the reason for some of the data being under
a less liberal license is to taint the live data feed that contains both
the core CC0 data and the Supplementary data.
MusicBrainz customers (such as BBC) then pay money to Musicbrainz to get
data updates every hour, which can be used for commercial purposes.

Nick, thanks for pointing that out - this had completely slipped out of
my mind, including in a conversation with Denny about Wikidata.
I believe the reason for the 'non-commercial' open license where
MusicBrainz add value is that they need to make revenue to support their
activities... including from the good folks at the BBC.

Are you saying they have no way to use CC-0? For past or even future
content? If both, can't they use PDM? If not, how can they say it's
PD?
MusicBrainz changed the license of their core data (everything that
matters) to CC0 a little while ago:

Nice, I see there's even a definition of "The core data of the
database". :)
It's still unclear to me why the use an unfree license for the rest.
