Any chance of avoiding this in the future by adding an "extensible,
but known to be suboptimal if used" extension field, so that these
kind of changes can be made without having to change anything
important to the point of incompatability?

That type of thing would let the problem be fixed in an ugly way,
but at least it would be fixed, without balancing things on a
knife's edge of incompatability vs. non-working code.
