I don't like it.

If we want '-H' to be like FreeBSD, that's one thing.

What I don't like about your suggestion is that what I think is the=20
underlying problem still isn't fixed. The underlying issue is that when=20
you add certain command options, such as -s, there's no way to suppress=20
options (columns) that they add. If such an option existed, you could add=
the -s option, this option, then build your own parsing option using the=20
-o option.

If we add 'H', then sure, we effectively have -s with the normal options. =
But we still haven't fixed the issue that you can't make a totally custom=
list of options.

Take care,
