package-inferred-system and :around-compile

I'd really like to use :around-compile (for use with local-package-aliases), but I can't seem to combine it with package-inferred-system as the inferred systems don't inherit the around-compile slot from the top level system. I'd happily supply a patch to enable it. But I'm not sure if it would make the most sense to just inherit around-compile from the top level system or add an additional initarg for the package-inferred-system class that gets passed to the inferred systems. -Eric
