 Replying to [comment:13 mcs]:
 > Opinions? The "swap the namespace" patch that we already posted is a lot
 simpler and we are confident that it disables MathML.  On the other hand,
 because the MathML namespace is lost, it breaks some assumptions made by
 web pages.

 > For the record, Kathy is firmly in the "let's go with the existing
 namespace patch" and I am undecided.  But I too do not like the extra
 complexity of approach 3, and MathML is probably uncommon enough that no
 one will complain about the namespace issue.

 Let's try the patch you already have then and see what breaks. Especially
 given the time constraints we have for the release and keeping in mind
 that there is #12827 waiting as well. Putting it back to needs_review
 again.
