This will also effect main-tests-rel (i.e. the main release tester).

RunTelemetryTests is called from:
  RunTelemetryUnitTests
  RunTelemetryPerfUnitTests

Note in GetTestStepCmds:
 ('telemetry_perf_unittests', RunTelemetryPerfUnitTests),

Finally, see in bb_run_bot.py that:
  telemetry_tests = ['telemetry_perf_unittests'] 
And telemetry_tests is used for main-tests-rel.

Do you know which bot is using main-tests-rel? main-tests-rel is mapped to
try-tests-rel. But it appears to me no bot is using it.

You are right. No bots are using it since we moved the main release tester to
recipes.

   bb_annotations.PrintNamedStep(step_name)
   RunCmd([run_tests_path] + args)
