Proposal: splitting the network package

I don't understand benefits of this plan. Consider another simpler
plan: we just provide two packages:
  - "network" without Network.URI
  - "network-uri" which includes Network.URI only (without the
    conditionals)

What is the difference Michael's one and this?

In other words, what does Michael's one contribute from the backward
compatibility point of view?
