Sourcing is a requirement from the very first edit made to an article. Not a nicety, not something you kinda work at before you're ready to bring it to FA or GA, a requirement. Just like articles should -never- be POV, they should -never- be unsourced. It's not "okay for a while."
You certainly know that that opinion doesn't reflect either current policy or practice on enwiki. About the only thing that's generally agreed upon is that sourcing is important. I have personally worked on adding sources to unsourced articles, but the articles were still quite useful to a reader before I added sources.
