Yes, I reference that table in a deeper comment. I didn't mean that it wasn't accurately documented, but rather that it's not immediately apparent. I know lots of people who were once quite experienced but still not enough to know what the attributes section is and its importance and its full meaning (myself included).
Indeed, surprising and easy to overlook was all I was trying to convey.
As many things, the behaviour is surprising and can be overlooked. But undocumented is not.
