All that said, I don't have a strong opinion on this.  Both the 1-word
approach (a pointer) and 24-word approach (embedding) are tolerable
and there are reasons to prefer each.

I do not care too much about 24-word wastage.  If this were not "a
pointer pretending to be embedded object", the fix in 1/3 wouldn't
have been necessary.  I am worried about this being an invitations
for such unnecesasry bugs.
