:Personally I find the tagging way way over the top, and I'm one of the staunchest WP:BLP/WP:RS editors you're likely to come across. I think if you re-read WP:BLP and WP:V you'll see that tagging every single iota of information within the article is excessive. To meet Wikipedia policy "It must be possible to attribute all information in Wikipedia to reliable, published sources that are appropriate for the content in question. However, in practice it is only necessary to provide inline citations for quotations and for any information that has been challenged or that is likely to be challenged" (this is directly from the lead of WP:V, the bolding and italics is my emphasis). If a specific role is challenged then it should be removed or tagged for citation, but not every sentence in an article requires an inline citation.
