multiple matching shapes and sh:closed

A node may be targeted by several shapes, right? Then all matching
shapes are applied?

We plan to use some distribution of property shapes along a class
hierarchy, eg:
- ex:PersonShape checks for field ex:name
- ex:PoliticianShape checks for extra fields ex:party and ex:politics.

The targeting could be done with RDFS inheritance (ex:PoliticianShape
rdfs:subClassOf  ex:PersonShape)
or the more flexible "semantic type targeting" we discussed before.

What to do if I want to say that a politician can have only those 3 props
(plus rdf:type) and no other?
I can't apply sh:closed to either of the shapes because it would close each
one individually but I need them closed collectively.

Guess I could use sh:and to put the two shapes together, but that would
double the work of checking ex:name
(because a politician also matches ex:PersonShape)
