C# Dependency Inclusion - PCL

Quick question-as referenced here, all third-party dependencies sent to the client must support PCL.

Can this restriction be removed?

No, for very obvious reasons only a limited API set can be supported.

Additional APIs can be added upon request, but must hold to the same safety standard as what is currently exposed.

@element.86 Could a sandbox environment be implemented?

No, any process token-level sandboxing is not sufficient/viable for these use cases.
