True, but if you are using GHC generated stuff via the GHC API you
sometimes do not want to have to implement Outputable for all your app
types, when you can auto derive Show which mostly does what you need.

Is there any reason I can't put in a diff request to replace the derived Show instance for SrcSpan with a handcrafted one that does not exhausively list the constructors, making it more readable?

Why? If you're looking for pretty output then you should be changing Outputable.
