This argues that co-evolution of an interface is easiest on the
developers if they own both sides of that interface. No quarrel.

This does not argue that that the preservation of a stable ABI is best
done this way. If anything, it makes it too easy to change both the
provider and the preferred user of the interface without noticing
unintentional breakage to forlorn out-of-your-tree clients.
