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."
Others have hinted at this, but let's take a look at the verifiability policy.
This page in a nutshell: Articles should contain only material that has been published by reliable sources. Editors adding or restoring material that has been challenged or is likely to be challenged, or quotations, must provide a reliable published source, or the material may be removed.
It does not say "If the article says the sky is blue, you need a source". Policy is that if something is challenged or likely to be challenged, THEN you need a source. Get that? Sourcing for non-controversial facts really is optional.
