Is self-correction of an operational failure ok after plan termination?

Can we self-correct an operational failure in a terminated plan or is correction of such failure only available by going to the IRS via VCP per Section 4.07 of Rev. Proc. 2021-30.  Section 4.07 doesn't say SCP is prohibited (unlike, for example, Section 4.08 which says SCP is not available to correct failures in orphaned plans).

It depends if the failure is originally eligible for SCP or not.
