As was pointed out to me in WGLC review of the MTLS document, "sender-constrained" has or is likely to be interpreted with a pretty specific meaning of the token being bound to the client and the client authenticating itself to the resource and the resource checking all that matches up. That makes

Kind of, yes. I guess so. I think. It's just semantics. But yeah. Key constrained might be more appropriate. But the Security Topics document probably should allow for both/either. I don't think that these are necessarily terms with widely agreed upon or understood meaning. But it was pointed out
