// Helper for determine trace category for high-level coarse mojo events:
// - If detailed mojo tracing is enabled, these events are not useful in most
// circumstances (e.g. they capture only interface name, while detailed mojo
// event tracing emits events which contain both interface and method names)
// apart from debugging mojo or trace events, so "disabled-by-default-mojom"
// category is used.
// - If detailed mojo tracing is disabled, then the passed category is used.
