Oh, sure, {,s}bin was just an example.  I don't really think 
there's a package manager that indexes only those two directories. 
'T would be silly.

Or ‘guix where’ or guix whatever.

(16 days left for someone to implement ‘guix whatever’.)

Well, we can deathmatch about the name and the number of hyphens 
once it does something.  ;-)

What do you mean by substitute index?

By complexity, I meant: if it would depend on a network connection 
to the build farm (or elsewhere), at all.

And would this information be provided by a naked ‘guix publish’? 
I guess that depends on the meaning of ‘substitute index’.
