Sandra suggested that:
I’d recommend removing the email update option for anyone who has ever donated via PayPal, not just exclusive PayPal donors. Since any past PayPal transaction could still be tied to the original email, we don’t want to trigger dedupe issues or mismatched receipts if the primary email is updated inconsistently.
Confirmed with Sandra on Aug20, only active recurring paypal matter.
