This makes sense, but the main requirement for CQ perf jobs to check if the change breaks any perf benchmarks. It is highly unlikely that disabling a benchmark would break anything, but incase if sheriff thinks the CQ is unnecessary then they can always remove the CQ_EXTRA_TRYBOTS from description and commit the CL.

+1 to what Prasad says. Doing static analysis on the code to know whether the CL is just a disable CL seems hard..

FWIW I actually managed to typo the disabled annotation a few times and these bots caught my mistake.

Ah ok, sounds like this is catching things :) Nevermind then!
