Every wikipedia link everywhere? That could seriously slow down the browser (Byblos won't do *.js kinds of things anyway).

But I can imagine a very short one for en.wikipedia.org.js (or choose your language) that would do it just to things on that site.

The most important bug to fix for 9.3.1 is issue 184 since that affects otherwise normal mobile sites (plus the security audit). Otherwise, I'm pretty happy with the mobile switchover.
