abbr and acronym

 I use both the abbr and the acronym extensively.  What is the reasoning
for not retaining acronym in XHTML 2?

 http://www.smackthemouse.com/20040108#h2-1 says ‘I am not going to
repeat all the arguments why it is impossible to distinguish between
ABBR and ACRONYM in any sensible way that is workable for web page
authors. This discussion is now history.’ without providing any
reference.

 Thank you in advance.
