This was one of the reasons behind
[[Category:Needs Profiles Created]]
This allows you to mark a profile that has say a census with wife and family without tossing crappy unsourced profiles out there just to fill in the holes. I would rather someone go back and look then carefully take their time getting the proper citation for each person added to the profile as it is being created while checking for pre-existing profiles of that person.
Honestly, many times I've just ignored relevant info in the past rather than making terrible profiles because I was working on something else.Great granpa had a second wife. Awesome. She had a mother and father. I don't care at that point. Skip? Now I can tag the wife who has info on parents and move on.
As far as promising to add sources later? LOL So funny unless someone is ACTIVELY working that section of the tree. Then I'd add this.
