This is exactly what I am getting at.  values does return more than 1
sexp, but the mechanisms for using that are clumsy and painful.  It
seems that if values returns multiple s-expressions, then they should be
treated as multiple s-expressions.  In between a set of parentheses, N
s-expressions are usually treated as N elements of a list.  Why should
values be any different?

(list 0 (values 1 2) 3)
==>
(0 #<values(1 2)> 3)

This is strange.  If we had

(list 0 (values 1 2) 3)
==>
(0 1 2 3)

Then multiple values would actually be useful.
