No, it would NOT be detrimental to the UX.
This is what Gestalt Principles is about and also my Talk for ActivityPub Conf was about.
This is stealing content and hiding content for the user.
If my friend on software bar decides to send me official type="xy" to my software foo the whole sense of the official protocol is that I get it !!!
“THE ENTIRETY” https://www.w3.org/TR/activitypub/#conformance

So, one wish:
If someone decides to show only a subset of an official protocol please do not pretend, it is the official protocol.
This is a very bad behaviour.
