The reason is that after the major bump, the API and ABI are declared to
be unstable for some period, so people can freely
- break ABI, e.g. by reordering struct members
- modify API added during the instability period in an arbitrary way
without a new major bump for every such change, that would be normally
required.
My concern is that the instability period is quite long and there is
very little indication for our users that they cannot depend on the
ABI/API being stable. So I'm proposing to introduce some mechanism to
make this more visible for our callers.
Alternatively, we could just not have an instability period at all.
