Createmeta REST endpoint to be removed

The documentation states that the Createmeta REST endpoint will be removed.

However, part of the way the document says to replace it is to use rest/api/2/issue/createmeta/{projectIdOrKey}/issuetypes and rest/api/2/issue/createmeta/{projectIdOrKey}/issuetypes/{issueT.
What is confusing is that this also is using createmeta. Does this mean that only when it ends in createdata such /jira/rest/api/2/issue/createmeta will it be deprecated? What about using rest/api/2/issue/createmeta?expand=projects.issuetypes.fields (which is what I need)?
