This is incorrect.  The Settings system and the RuntimeEnabledFeatures system
are separate and should not be linked.

@abarth, @tonyg,
Currently, this setting is used as controller in perf tests.
If they are not allowed to be linked, Is it possible to remove this setting,
then pass the content_switch to perftests? I'm not familiar with perf test
harness.

thanks
Pan
