Is this still true?

Note: The greater-than and less-than operators (> and <) result in key ranges that are inclusive of the terms. There is no supported notion of “strictly” greater-than or less-than; these operators are merely supported as aliases to >= and <=.

I think that making > and < aliases of >= and <= is a terrible idea!

First of all, it is very misleading. Second, what will happen to old code when > and < are really supported? (Some day they will be supported!)
