Indeed, given such a SRFI, I question whether SRFI 195 actually adds anything.   It seems simpler just to continue to restrict boxes to hold a single object which can be converted to and from multiple values.

It's a different abstraction.

Furthermore, in Schemes where a multiple box is implemented through
native reified multiple values, it would less efficient to put a, say,
vector in a box holding exactly one value.
