I will assume that priority boarding will still exist for extra room and airline branded credit cards that previously had this perk
From Delta:
Adjustments to the boarding process to encourage more space for safer travel. As of April 10, all flights follow a back-to-front boarding process to reduce the instances of customers needing to pass by one another to reach their seat. The measures will be in place through June 30 and may be adjusted or extended depending on COVID-19 developments.
Pre-boarding, as always, includes those who need extra time and assistance. During the main boarding process, customers will be invited to board by rows, starting from the rear of the aircraft, forward.
Customers are encouraged to help create more space for each other by waiting for their row to be called. Those seated in Delta One or First Class, as well as Diamond Medallion Members, remain welcome to board at any point during the boarding process, while respecting the need to provide space to all customers who are boarding.
The new process builds on the metered, or spaced, boarding that began in early April, and boards fewer customers at a time to allow for more distance between them.
