It turns out that the last time a major version didn't have a unique
control file version was 9.5, I assume that's where David is coming
from.

That said, I don't think it's a good practice to use the control file
version as an identifier for the major version. Who knows, it might be
necessary to add an optional new format in a minor version at some point
or such crazyness. And then there's the beta stuff you'd mentioned, etc.
