The problem is that there are plenty of Web contents that only target
WebKit or Trident (especially mobile for the former and non-mobile for the
latter), and they will likely be broken if we make this change. On other
hand, there can't possibly a backward compatibility issue for contents that
only target Gecko or Presto because they have mandated the parameter
according to Aryeh's research.

I agree that it would have been much nicer if we had defaulted to true
years ago or mandated the parameter, but that ship has already sailed.
