There is also the chromeos_x86-generic_chromium_compile_only_ng bot on
tryserver.chromium.linux .

Also, we should remove the builders before we actually land this change;
otherwise the builds will start to fail.

Ah, thanks, removed.
Could you clarify "remove the builders"? What builds would start to fail?
Thanks!
