Yes, it's an unfortunate breakage, but it's also a modern spam
mitigation technique, and it's slowly gaining steam amongst the bigger
free providers (there were rumours of gmail setting "p=reject" in 2017).

I feel your pain. I sympathise with mailing list managers - I've had the
displeasure of running Mailman once myself.
As an aside, it looks like Mailman 3 has switched from pipermail to
hyperkitty, which might provide the obfuscation/hiding of email
addresses that you're looking for.
