Is this worth the extra complexity ? X32 has very little adoption. Does it even make sense in the context of a browser ?

Comment on attachment 197712 [details] Rebased again Cleared flag to remove from review queue. It doesn't seem like X32 has enough adoption to warrant it being added to our shipping browser code.

It looks like x32 support is not planned at this time.
