Should we allow compatible API additions to a library in a minor release of the platform?
The choice is between allowing only bug fixes in minor releases, or also allowing new features that add APIs but do not change any existing APIs.
How has this been handled historically by the GHC team?
I think I am correct in saying that for the most part there have been no API additions to the base/core libs in minor GHC releases. In some cases there have been exceptions in less frequently used modules like GHC.* and we have on one occasion shipped an updated Cabal library in a minor version that exposed some new API (but not one that most Setup.hs scripts were intended to).
