I agree.

However, R7RS abandoned this for records, presumably for a good reason.

R7RS-small left this unspecified, leaving room for WG2 to fill in the gap.

I think the best thing all around is to treat boxes as what they are - simple

single-valued records - and let the record specification apply to them.

Anything else is confusing.
