Domain Separation, Type = MSP

I think I understand but want to make sure. When using domain separation, each domain is given a "Type" choice (OOB) of MSP, Customer, Vendor. From what I can tell the type of domain is simply for categorization and does not bring any functionality along with it. Visibility is dictated by contains and visibility domain while access to functionality such as domain picker, toggle domain scope, etc. are controlled by role.

Is there any functionality that I'm missing from a domain type = MSP perspective within domain separation?

Thanks,
