P.S. Could someone please remind me why containers ships with GHC?

Some other packages shipped with GHC depend on containers, e.g. hoopl, template-haskell, haskeline, binary.

So GHC uses some packages in its implementation, but that shouldn't have to mean that it also needs to export these. Is this a technical issue?

GHC needs to ship with anything that ghc-the-library transitively depends on, yes.

As a thought experiment lets consider what would happen if GHC would like to use unordered-containers in its implementation. Should GHC now be making releases to unordered-containers? That doesn't sound like a good thing.

There are certainly disadvantages to making GHC use a library. yes. We have to weigh them up against the advantages we get from using the library. Thanks Ian
