Disable / Delay "Warning: modules not listed in *.cabal for '*' component (add to other-modules):" Warning

From what I can tell, the `other-modules` field in a cabal file only matters when packaging for a Hackage upload. Cold this warning instead be emitted during the upload check or could we have a flag to disable this warning? It seems pointless to manually maintain a module list or see this warning on every single build for projects that won't end up on Hackage.
