Probably best to clearly state where I currently stand: 1. Now that I've seen how a restricted method gets marked up in the javadoc with the very prominent text and link to the restricted-methods page, I think that addresses my concern about each restricted method documenting what happens if there is no caller. 2. I do think there should be some description as to why a given method is declared "restricted", as it may not be obvious. But I will agree with Alan that this can addressed separately as needed. 3. I will just note that the description for this issue is "Clarify handling of restricted and caller-sensitive methods" but there is nothing in the proposed changes that relate to CS methods, and I think we have agreed that any documentation that may be lacking for pre-existing CS methods should also be handled outside this PR.
