class LateBindingTracerProvider

Late binding providers are designed to be used by Instrumentation, while we do not have control over when all components (propagators, etc) which are registered through composer.autoload.files are actually loaded. It means that tracers etc are not fetched from Globals until the last possible instant (ie, when they try to create a span, get an instrument, etc). In the future, when everything uses SPI, this will be removed.
