I wouldn’t consider a consumer-grade router that doesn’t have OpenWRT support. No arbitrary EOL to worry about. I was very happy with OpenWRT until I moved to OPNsense router and Ubiquiti access points. I still use it on my travel router, too.

Edit: Check if your current router is supported by OpenWRT and get more life out of it.

Lots of discussion here of Zed being macOS-only. Multiplatform support is being tracked in this issue for Linux, Windows, and web:
