Deniable backdoors are a much bigger risk than reproducible backdoors. I trust my hardware manufacturers to be afraid of putting a backdoor into their chips if a binary captured via network surveillance could be used to show that a backdoor existed. This would be devastating to their business. Therefore, I trust them to not do anything that risks this occurring. This is why people were so uneasy when internally-accessible unique serial numbers were added to the microcode engines of Intel processors.
