Mobile Commons: What is the expected behavior for the default opt-in paths?

Confirmed the expected behavior for the default opt-in paths. 

• The default opt-in paths do not require any keywords to be added.
• The purpose of the default opt-in paths is to send a unified message to profiles that are opted out, have no subscriptions that send any unidentified messages to the SC, or active subscribers that respond with unidentified replies outside the conversation cutoff time(Default of 72 hours).
• This response is not sent to active subscribers; it only applies to unsubscribed profiles.

 NOTE: We recommend maintaining a dedicated campaign exclusively for the default opt-in path. This campaign should not be used for any other purposes, such as broadcasts or creating other opt-in paths.
