For sure we cannot reference a spec that is not frozen yet (i.e. platform/profile). ISA_SPEC_CLASS_FROZEN_2021 was a proposal for all groups of ISA extensions that have been frozen in 2021 (zb*, zk*, etc.) and will eventually be ratified. But yes, keeping NONE until the specifications are ratified and change the specification class then is also possible.
