After all, it might be an IE only meta tag / HTTP header, since other
browser developers are not too happy with it, there are lots of
possible problems:

So the FF=3, OtherUA=4 part there is simple speculation right now. The
Mozilla arguments are:

 - the browser needs to ship with multiple rendering engines for all
users (higher footprint)
 - an iframe in IE6 mode might need to communicate with a document in
IE8 mode (different APIs, different DOMs)
 - you cannot freeze the IE6 engine, you need to maintain it
"forever", because you ship with it, so you need to solve bugs /
security issues (which might break APIs)
 - also more attack possibilities since you have more engines installed

So it does not look like the other browsers are following suite.
