As a member of the community of people unable to read minds and pick up on social cues (!), I find someone not telling me where they stand on a particular thing to be worse for me than if they outright said yes or no.
E.g. if I expressed interest to meet a friend for the first time, and they just completely went silent, that is more torturous and excruciating than if they came back and said "thanks for the offer but no thanks" (or words to that effect).
With the example you have provided, it would drive me crazy if there wasn't even an, "Can I sleep on it and get back to you?" Complete silence would be likely to result in me thinking that the idea didn't appeal to them (for whatever reason), and that maybe they were worried I would be upset or take offence if they turned down the invitation.
In that situation, giving someone a clear idea of where they stand strikes me as common courtesy.
Yep. Even considering the person's own anxiety etc, I think it's disrespectful to not let the person know.
Okay, if the person is blatantly horrible and abusive, then that's a separate thing, but if it's someone who's actually trying to be nice, then it's a massive slap in the face.
