Many cases I knew, people would have several repeaters and extra routers to extend coverage in big houses, and not set it up correctly in PA/Bridge mode, so peripheral network devices would be locked behind in a separate NAT’ed subnet.
I've dealt with this a ton trying to help troubleshoot people's home network problems during the early days of COVID WFH. [1] Some of the absolute messes I'd see were astounding, and they thought everything worked fine because all their phones and Apple TVs and kids PCs running Steam could all get to their cloud stuff fine, so why couldn't their company laptop talk to the printer they brought home and plugged into the "router" in the basement?
[1] Not something we'd /normally/ do, but when that was going on... You just had to get people working.
We can consider it, but Miele won’t. Their problem is connecting your washer to your phone and going through the cloud has other side benefits for them as well, such as telemetry, so here we are and will be.
