I am not sure.

On the one hand, the catalogs don't promise to be a stable API, so there
would be no need to enumerate such changes as compatibility breaks.
The "Migration" section also doesn't list changes to the exported
PostgreSQL functins, which has bitten me as extension developer several
times.

On the other hand, the catalogs are described in the documentation, which
gives them more exposure, and it doesn't seem unreasonable to document
breaking changes as well.

Do you have an idea how many changes there are?  If there are not too many,
and somebody is willing to do the work, I wouldn't be against it.
