I’m wondering whether it makes sense to have this theory (a 17 KB file) in the Library when our main theory Finite_Set.thy (60 KB) is part of the standard HOL development. Of course we are all against bloat, but the separation of this material from the other material looks artificial.

I remember other people suggesting this as well, albeit not on this list. It 
seems fair to me. Only the function atmost_one at the very end should go 
somewhere else.
