The parameter name "--apparent-size" is not likely to be changed.
It has been named so for about 16 years (since 'fileutils 4.5.8'
which is even before 'coreutils' was created as a unified package).

Changing it would break existing scripts and user expectations.

Creating a second alias to "--apparent-size" is possible, but I'm not
sure it's warranted.

I think the discussion about "--apparent-size" is mostly concluded,
but the idea to have two-columns is an interesting feature request.

I'm marking this as a "wish list" item.
Concrete patches are welcomed.
