    ...Although if the whole application is just **crashing immediately** it probably doesn't make sense to keep restarting it forever. But in those cases, you will probably notice it during development, or at least right after deployment.

	// Without this logic, there are cases where the clusters we send could stay warming forever,
	// expecting an EDS response. Note that in SotW, Envoy sends an EDS request after the delayed
	// CDS request; however, this is not guaranteed in delta, and has been observed to cause issues
	// with EDS and SDS.
	// This can happen with the following sequence
