It works well if you self host with your own domain! Grewt piece of kit, really

Depends on what header they read and how

I dont think so. I get my self hosted aliases banned. They must read the dkim/spf/dmarc or other types of headers against a base of mainstream email providers

Typical Google: 'everything needs to constantly change for nothing to evolve at all'

I think you are on to something, mr Whistleblower. Keep digging and call Greta when you have drawn conclusions! In the meantime, move stealthily, they may be watching! :-)
