Would it not be better for this to depend on a symbol that systems can
select when they add useful output?  If there's nothing that generates
information for it on a given platform there's no point in enabling it.

It is deactivated by default when "default" parameter is not mentioned.

That's not the point - if the user sees the option and turns it on then
there won't be anything they can actually do with it unless some other
bit of software creates some data.  No sense in offering them an option
they can't actually use.
