I realized later that we might as well write the LSN at the time of the file creation. That would remove the need to make the first page of the binlog file dirty whenever anything in the file is being modified. File creation may have to durably write the first page for this scheme to work. For normal .ibd file creation, this kind of a step was removed in https://jira.mariadb.org/browse/MDEV-24626.
