The reason the client would ask for claims in the ID token is likely because:

a:  The IdP doesn't have a user_info endpoint (Mobile Device) and knows it MUSTask for them in the id_token if it wants them.
b:  The Client is trying to reduce the latency on getting some of the claims.

In general I wouldn't expect to confuse a user with making a choice around this.  It is the IdP that needs to decide.  
In the self issued case the claims are always going to be in the id_token, the claims_in_id_token scope would always need to be treated as if it were present.
