No removal date was declared in either the changelog notice or the community announcement. And I’m not aware of any targeted removal date.
That said, I can’t recommend using a deprecated endpoint (that’s kind of definitional). Rather, I would recommend getting the change of scope logged as a suggestion so you, and others who might stumble upon this thread, would have something formal to track. Could you please open a “suggestion” issue yourself in our open Jira (JAC) in the JRACLOUD project. I think you could just copy/paste your opening post. Once you have the issue key, please let us know here so other folks can watch, vote, and comment.
