CfC: ActivityPub errata on inconsistencies in the side effects of receiving a Follow activity

Issue #320 in the ActivityPub repository points out a discrepancy 
between sections 5.3 and section 7.5 of the document:

https://github.com/w3c/activitypub/issues/320

Roughly, the problem is that one section describes the `followers` 
collection as every actor that has sent a Follow activity; the other 
section describes the approval process for being added to `followers`.

To correct this problem, during issue triage, I've added two proposed 
errata:

https://www.w3.org/wiki/ActivityPub_errata/Proposed

The first is:

  * Section 5.3 "Followers Collection" should begin,/Every actor SHOULD
    have a followers collection. This is where one would find a list of
    all the actors that are following the actor./

The second:

  * In section 7.5 "Follow Activity", the second paragraph is incorrect,
    and should be removed.

This is a call for consensus for adding these two errata to our errata 
page for ActivityPub:

https://www.w3.org/wiki/ActivityPub_errata

If, in 14 days, we have no objections on the list, the errata will be 
added. I'll also apply the changes described to the "editor's draft" of 
the document.
