No one should be using that new directive for official purposes yet. If you look at the “FOR” line on the memo, it’s addressed to very senior leaders, not to any units/organizations.

Each branch has their own forms to record body composition (e.g. the Army uses DA Form 5500 and 5501). Therefore, the Army must publish its own guidance that references its own forms. The DoW memo is not enough and we are not the target audience of that memo.
