I find it frustrating when you ask “are there plans to…”. Calcite is a volunteer project. I don’t know what other contributors are doing, and I don’t control their time. If someone is working on something, they will have logged a JIRA case and marked it “in progress” or set the “fix version” field. If you had done a search, you would have found a JIRA case [1]; it has been inactive for 2 years.
If you really want this function, contribute a patch.
