IMO, the situation is not going to get better until WikiTree (us) can clean up their own act.
Remember this thread from not too long ago?:

How can we expect anybody to follow some sort of guidelines, when the existing published ones are confusing and overbearing to begin with?
There needs to be a range of things that people can do to improve their sourcing without getting pedantic about "Chicago Manual of Style". This is not University and people should stop getting so uptight about it.
FamilySearch should be the first place to go for sourcing. It's easy to copy and paste the citation that they give you. There needs to be tutorial on how to use it.
I've always liked the guiding principle that a source should be complete enough that someone else should be able to reference it and determine the data for themselves. If one goes with that principle, then it doesn't matter the exact pedantic style of the format. It's all about if the information is complete.
I've had a run-in recently with a woman who was a Profile Manager who got so uptight about the spacing of the sources in a profile (I like to put in a blank line between them for readability, she takes them out), and also said that there shouldn't be a link to Find A Grave, when there is already a FamilySearch citation to the Find A Grave link. She believes that that constitutes a duplicate source and removed it. I said that I put the Find A Grave link in there for the convenience of other people, because otherwise you have to go to FamilySearch, and then know to click another button to take you to Find A Grave.
And all of this is on an older profile where there should be no "ownership" felt by anyone, but it's just under the 200-year limit . Why are there stupid arguments over the exact nature of what should or should not be in a profile? There are not enough good guidelines for how to use WikiTree, the goals of WikiTree, what is acceptable behavior and not acceptable behavior, and policies that make fixes to many things too slow, which encourages apathy.
Any guidelines should be clear, consistent, and easy for the average user to do, with tutorials on how to do it. Lower the bar a little, in order to gain real improvements. If the bar is too high, you'll get nothing.
