Identical UA treatment seems *far* more important w.r.t. removing 
confusion, than anything else. *That* is where the claimed confusion 
is. Further: HTTP-EQUIV Content-Language would only be un-permitted in 
HTML5 documents and not, for example, in XHTML 1.1. You will continue 
to have to explain both that *and* the fact that using http-equiv will 
still work.

On the positive side (to not only be negative), the removal proposal 
treats multiple tags and single tags as equally un-conforming.  But I 
do want to call to your attention that by supporting this proposal, the 
I18NWG will be supporting a proposal which continues to draw a link 
between @lang and Content-Language:

+    <p class="note">This feature is non-conforming. Authors are
+    encouraged to use the <code title="attr-lang">lang</code>
+    attribute instead.</p>

The above is the same that HTML4 says. So where is the clarification? 
You must be putting high hopes in the validation error message ...
