[Pro Sites] Paypal Changes to Affect Pro Sites or Fundraising?

I received the following notification from Paypal, and need to know if these changes will affect functionality or in any way interrupt ongoing subscriptions created via our Pro Sites and/or Fundraising plugins.

While the FAQ suggests no integration changes are required, based on past experience I'm looking for reassurance from the developers since it does discuss IPN and certain subscription functionality.

Thank You!

Initial Notification : Effective February 1, 2019, PayPal will make a change to PayPal Payments Standard Subscriptions features Modify and usr_manage. If your integration includes these features, you'll no longer see the same functionality.
