Yes, but that isn't actually something to complain about.  It turns out
that none of the rendering engines were actually obeying version 2, so
version 2.1 was released as a pragmatic way of having a standard that's
based on reality.

I'm not sure how misguided it is, especially if done well.  For example
a site that only works in 'IE' usually checks for the string "MSIE" in
there.  So 'Opera' in 'IE'-spoofing mode includes that string -- but it
still leaves "Opera" in there too.  So by checking for 'Opera', gecko,
and so on before 'IE' you avoid most of the spoofing problems.
