Automatic Enrollment under SECURE 2.0

What is your interpretation of the new automatic enrollment rules under SECURE 2.0 for a plan being established as a QACA?

Do the new rules (i.e., 3% minimum default; auto increases of 1% per year up to 10%, and not more than 15%, if default % is less than 10%) need to be applied to the plan, or can you abide by the old rules for QACA (i.e., any % for a default; auto increases of 1% per year up to 6%, and not more than 15%, if default % is less than 6%)?

Thank you in advance for your reply.

Simplified version:

New rules (Sec 101(b)) if the plan is established after enactment of S2.0.  

Unless you fit one of the exceptions in Sec 101(c) of course.
