Why does trivial class have a new requirement that the class have "at least one non-deleted copy constructor, move constructor, copy assignment operator, or move assignment operator." This doesn't seem logical to me.
I'm sure there is a paper on this somewhere but I would not know how to find it.

The first link, http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0167r1.html, has "Additional note, November, 2014: See paper N4148."
https://isocpp.org/files/papers/n4148.html seem to be the right paper.
(should have sent the e-mail to the list)
