Are the newly introduced links available as an endpoint? In v1/thesaurus, I don't see the links under the respective keywords listed?
No. Didn't bother.
Not many users write apps these days anymore, and always implementing all enhancements in all IMWS endpoints is just not worth the time.
I implement them when I need them in an app that is useful for all users, but not in general anymore.
Just not enough users writing apps to spend time keeping everything up-to-date all the time.
Feel free to post a feature request.
