* Release a new version of network (1.5) that does not include the Network.URI module. * Create a network-uri package that uses conditionals in the cabal file. * If it's compiled against network version 1.4 or earlier, it doesn't provide any modules. * If it's compiled against network 1.5 or later, it provides the Network.URI module.
This way, there's only ever one package which is providing Network.URI.
Alas, this causes some of the conditional-API issues mentioned in [1], specifically the following situation: Say, I have a package which specifies only its dependancy on 'network-uri' (but not 'network') for its 'Network.URI' module, then the package compilation breaks depending on the actual version of the 'network' package linked against.
