I tried installing the latest 25H2 (stable iso) and nothing has changed so far. You can still use "bypassNRO" to set it up with a local account, offline. The planned changes will likely only affect the Home edition (Pro/Ent/Edu have more options). Even with Home edition there's a good chance you'll be able to make a local account with an answer file[1][2] or an unofficial tweak.
I think Windows will always be able to work without a MS account, because there are many critical (offline) deployments out there. But they'll probably make it difficult if you're using a "consumer" edition.
