Which is probably not terribly important. Few, if any, buffer changing
primitives have been implemented in the last 20 years, and it's
difficult to foresee that any new ones will be written in the next 20
years.

So the flexibility you gain by permitting non-balancing of the change
hooks is the ability to write unbalanced change hooks. Somehow, I'm a
bit underwhelmed.
