The word "default" is part of what I find confusing here. It's obviously not the default, or there would be no need to define it. All implementations have a *default* semantic for those elements, but sometimes that default is not according to spec. I think what you trying to convey here is "Should authors explicitly define the ARIA semantic that should-be-but-is-not-actually the default?" Obviously you don't want a title that long, but I still think your meaning is unclear with your current phrasing.

I see now my phrasing in the form of a question was rather unclear. Apologies.

I understood what NO meant in this context but was trying to convey the confusion that other readers might have when reading this table, based on that easily misconstrued header title.
