Comment:

 There are two problems here:

 * duplicate content, in default installations and many themes who do not
 do anything special with comments - so default canonical URL would be
 appropriate for them;
 * some themes or comment systems like Diquis have special use for
 "comments page 1", so they depend on current solution.

 My proposal is different: change core to force canonical comments page URL
 by default. Additionally provide way to disable it, e.g. by deregistering
 some action hook or using new "pre" filter. This way both group of users
 will be happy by having good default implementation, and having way to
 disable default if they want to do differently.
