But if you change the mapping convention between files and module names, you need to do it for all tools, not just the compiler.  I imagine all of the following tools would need to know about it:

So actually many of these tools don't need to map module names to source 
files, so they work unchanged.  Only Cabal definitely needs changes, I'm 
not sure about hoogle and hat but I suspect they would be fine.

Fair enough :)
