// Encapsulates the platform-specific configuration for the ThreadProfiler.
//
// The interface functions this class make a distinction between 'supported' and
// 'enabled' state. Supported means the profiler can be run in *some*
// circumstances for *some* fraction of the population on the platform/{released
// Chrome channel, development/CQ build} combination. This state is intended to
// enable experiment reporting. This avoids spamming UMA with experiment state
// on platforms/channels where the profiler is not being run.
//
// Enabled means we chose to the run the profiler on at least some threads on a
// platform/{released Chrome channel, development/CQ build} combination that is
// configured for profiling. The overall enable/disable state should be reported
// to UMA in this case.
//
// The std::optional<version_info::Channel> release_channel passed to functions
// in this interface should be the channel for released Chrome and nullopt for
// development/CQ builds.
