Dear Tobias,

I personally think this "weakly-depends-on" is a horrible mess.

If you want FOO, require FOO. If you want FOO+READTABLE, require FOO+READTABLE.

And so have two systems FOO and FOO+READTABLE. I think that's what the
dwim.hu guys now do. It also works better with XCVB, this way.

I think this can be external to ASDF itself. At ITA, we have scripts
that do things like that. My, it's ugly. Trying to get rid of it.
