Long time ago [1] it was decided that category net-www should be
retired, since the www-* categories exist for these packages.

However, if I look at the category, then most packages in it were
created in 2006 or later. In my understanding, at least no new
packages should be created in net-www.

Another question is if the existing ones should still be moved to
some www-* category?
