> And that's for good reason. Encyclopedias are supposed to be tertiary sources, not primary sources. Having an explicit cited reference makes it easier to judge the veracity of a statement compared to digging through the page history to figure out if a line was added by a person who happens to be an expert.
But why is a reference to "[1] Blog post by XXX" (or, even worse, "[1] Blog post by YYY based on their tentative understanding of XXX") a more authoritative source than "[1] Added to Wikipedia personally by XXX"? Of course, Wikipedia potentially has no proof that the editor was actually XXX in the latter case; but they have even less proof that a blog post purporting to be by XXX actually is.
