Empty user 'favourite' subpages should noindex

[jonoaldersonwp]

When a user profile 'subpage' is empty (i.e., "no favourites", or "no topic replies"), we should:

• Remove the canonical URL tag
• Add a meta robots tag with a noindex, follow valaue.

E.g:
​https://wordpress.org/support/users/jonoaldersonwp/favorites/
​https://wordpress.org/support/users/jonoaldersonwp/topics/

But NOT

​https://wordpress.org/support/users/jonoaldersonwp/replies/
​https://wordpress.org/support/users/jonoaldersonwp/subscriptions/

Is there really any reason for any of the ​https://wordpress.org/support/users/$user/$subpage to be indexed?

Seems like noindex, follow makes sense for all of them.

I think there were some objections to this originally, but I'd be very happy to noindex, follow them.
