HATEOAS might make a come back as it might be useful to expose an API to AI agents that would browse a service.

On the other hand, agents could as well understand an OpenAPI document, as the description of each path/schema can be much more verbose than HATEOAS. There is a reason why OpenAPI-style API are favored: less verbosity of payload. If cost of agents is based on their consumption/production of tokens, verbosity matters.
