Description

Mailboxes/get should conform [the rule of using capabilities](https://jmap.io/spec-core.html#the-request-object):

> using: String[] The set of capabilities the client wishes to use. The client MAY include capability identifiers even if the method calls it makes do not utilise those capabilities.

constraints

• return `unknownCapability` request-level error on unknown capabilities
• return *what* on not supported capabilities ?
• return altered results for effective capabilities. But I don't see any capability can make effect on Mailboxes/Get

DOD:

• Register capabilities by a static field.
• Implement capabilities validation
• Implement capability effects on each processed objects (provide a generic mechanism)
• Tests
