I think it's best to only buy routers supporting openwrt in the first place and switch firmware to openwrt asap. Openwrt or Opnsense or anything open source and well maintained will guarantee security updates years and years beyond the original manufactures firmware.
Have you ever used a EdgeRouter?
No, but openwrt seems to be available for some of their models if that is your question.
