This inconsistency is there in the documentation already, compare:

  :type-error "This field should contain an integer"

With:

 @item integer
 The value must be an integer.

Sorting it out seems beyond the scope of this bug report.  If we even
need to do anything about it.

I basically agree, but we use "must" and "should" interchangeably all
over Emacs.  In context, they mean more or less the same thing.
