Yep, our push server knows which keys are in which device ids if you activated Push Notifications. But that into is not public, only the push server sees it. Device IDs are random numbers, so they don't expose any other info about you.
But if you are concerned about that, you should know that if you use multiple keys in the same device, relays and image servers, including proxies, can also see which keys are together by just logging where requests are coming from. They can do that roughly well even through Tor.
VPNs can muddle this info, but the VPN server itself will also know that info (and much more).
Happy to code schemes that obfuscate that info, but to the best of my knowledge, Signal, SimpleX servers also know the same info based on Device IDs/IP info.
