We implemented it in NC-Verilog as written, without reserving "none" as a
keyword. We allowed any of the net type keywords or the identifier "none".
That was how I interpreted the standard. It is a bit of a hack, but
directives accept some strange syntax already. For example in
`timescale 1ns/1ns
"ns" isn't a reserved word. It is just a set of characters that are legal
in that position in the directive, like "none" in `default_nettype.
So I wouldn't consider this an erratum. Others might disagree.
