Understood. I think we just differ on where we keep our tertiary information.
I cite teriary sources when I don't have anything better, and then I don't consider it the end of the matter. I'll generally say something like, "John Doe, XYZ.COM/Smith.html, citing no sources." (and I'll take a screenshot of the site as my local copy) as an alert that further investigation is required. I might even add a further discussion as to why I think John Doe's information may be problematic but still useful.
Maybe it's a holdover from TMG, which had a surety field for rating a source's reliability. FTM used to have that as well; why's it missing from the current version?
