FHIR-23707 asserts that the use of minValueSet is a 'SHOULD'.  I strongly argue this is not true.  The vast majority of places where FHIR implementation guides mark elements as mustSupport with either required or extensible bindings, there is no need for declaring minValueSet and, in fact, no chance of agreeing to them.  This should be changed to 'may'.  We might want to add some guidance on when having a minValueSet is appropriate, but it's not a generic SHOULD across all specifications.
