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.
