That would be great, if anything about the current rules is incorrect or
out of date.

There's no reason per se to limit it to only the range for currently
defined wifi channels if the regulatory body allows unlicensed use of a
wider range. But the rule should include the entire channel bandwith and
not stop at the center frequencies.

It's a direct conversion between the dBm and mW values (in fact mW
values in the text database are converted to dBm values for the binary
database), so the units in the text file don't matter all that much. But
I don't really like changing the units just for the sake of changing
them when the values are already correct; there's always the chance that
some mistake will slip in.
