Support "parent" field for issues from company-managed projects

Are there any plans to support “parent” field for issues from company-managed projects in near future?
It would be great to find out issue’s “parent” while searching for an issue (https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-search/#api-rest-api-3-search-post) and modify “parent” while editing issue (https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-put) in same way as it currently can be done for issues from team-managed projects.

It has been mentioned here (Jira issues suddenly misses "parent" field - #6 by ThomasEhmann) that there was an attempt to introduce “parent” realtionship for company-managed projects. Are there any plans to return to this idea in the near future?
