That function could have been left in the API and marked as "deprecated"
or something.

The V4 version is supposed to break the API with previous versions and  as such there should not be any function marked as deprecated.

IMHO, I don't think that removing functions from the API in each new
release is a good approach, even if there is a good reason for that. It
will break lots of compilations out there.

I totally agree, and this will be the rule for future versions based on the V4 ABI.
