Agreed.

The patch below is my first attempt at removing these three outdated
copies and the machinery around them.

There is just one catch: doc/xml/manual/intro.xml has 132 links to
../ext/lwg-defects.html#2442 (and other anchors).  

I could just replace this with the upstream link all those times, but 
am wondering whether there is a more elegant way using SGML/Docbook 
that you could help with?

What do you think?
