2020 NEC code changes
NEC 2020 is not a law.  It is a model law, which states and municipalities are free to adopt or adapt as their law.  

Your state decides when (or if) which parts of 2020 NEC become law.  I expect places like CA where exterior panels and disconnects are common, will probably acquiesce to exterior disconnects, and places like IN or OH where they are uncommon, will not.
