The most useful information is like this (let's say someone orders 
"cabal install -v3 x"):

will add array-0.4.999 for
   x-2.3's array >= 0.4.999
   containers-0.4.2.1's array any
   Cabal-1.14.0's array >= 0.1 && < 0.5
   ignoring existing array-0.4.0.0
will replace containers-0.4.2.1 for
   Cabal-1.14.0's containers >= 0.1 && < 0.5
   change of array
   ignoring existing containers-0.4.2.1
will replace Cabal-1.14.0 for
   x-2.3's Cabal >= 1.12
   change of array, containers, process
   ignoring existing Cabal-1.14.0
will add x-2.3 for
   command's x any

(remark: change of process happened in a previous session and noticed now)

Most of this information is not found the output of cabal install -v3.
