My plan for ASDF 1.600 is to rename the (recently) builtin asdf-binary-locations to asdf-output-locations and make a few incompatible changes to it.
Please don't. I don't have time for a long explanation; but A-B-L is a completely accurate description of 90% of what it does, and ASDF has certain options completely backwards. (I think it inherited these from the single-user/single-address-space lisp machine mentality.) Rather than institutionalize these, I think there are straightforward ways to start turning towards a better path.
Please ping me if I don't get back to this in a couple days (I had a few comments to make re 1.5.0 that have also languished). Or maybe we could meet somewhere to hash out some better ideas.
