I think that it's not a good way to ask the user to provide certain
command-line flags. When we add 'private' to the code, the user is free
to enable or disable the warning. Otherwise, we would choose for him. I
prefer freedom for the user...

Another option would be a work-around in the code which disables the
warning locally. We have cases where this is used, but in the above
case, I don't think it's the easiest solution.

I wonder if it's possible to distinguish regressions into "fail" and "not
supported", where the latter means that it fails and we (currently?)
can't make it work. This way it might be easier to find regressions that
are supposed to work but fail because of "accidents" :)
