Can be. But I really hope that we will able to do everything during Phase 2. That is my plan. And the God is smiling when human do plans. :)
Actually, @Mirek shouldn't the Phase 2 be "SPDX is mandatory for new packages from certain point in time" instead followed by Phase 3 with complete migration to SPDX?
I was thinking that Phase 1 (the point at which SPDX ids are officially adopted and the various tasks noted in the Change proposal) would mean: SPDX ids are mandatory for new packages as of DATE.
Phase 2 would then be all about how to most efficiently get existing package spec files updated - which will be a longer phase.
