I understand that. I was just wondering if, historically, breaking
semantics w.r.t. plain arrays (and aligning on existing containers
instead) has always been a design choice or it "just happened" because
of multiple papers in flight at the same time.

* array was added to TR1 in ~2003 (N1548, N1475)
* then got merged into the draft in ~2006 (N2003)
* ref qualifiers on *this was proposed in ~2005 (N1821)
