Why Atlassian removed worklog related fields from the newly created next-gen projects?

It seems that few days ago Atlassian removed such fields like worklogDate, worklogAuthor and worklogComment from the fields searchable via JQL.

How to reproduce that?

  1. Create a new next-gen project

  2. Log time

  3. Try to search for that issue using the mentioned fields.

Expected results: the issue can be found

Actual results: the issue cannot be found

The next-gen projects created earlier still works as expected, i.e. issues can be found using the mentioned fields.

Is there any reasoning behind that? Or maybe it is a bug?
