But we can still buy old models:

> As outlined below, today’s action does not impact a consumer’s continued use of routers they previously acquired. Nor does it prevent retailers from continuing to sell, import, or market router models approved previously through the FCC’s equipment authorization process. By operation of the FCC’s Covered List rules, the restrictions imposed today apply to new device models.

I’m sure plenty of US factories are capable of importing boxes that look like routers but are actually just switches (because the router firmware is missing) and re-flashing them here…

I suspect "evergreen" model numbering/naming will become even more common in the future.
