The issue is you're going to have the ignorant customers calling Netgear to complain their brand new router is not secure if their browser highlights it for situation #1. Same for an untrusted certificate. The risk with #2 is then an attacker could potentially probe the firmware to figure out that process, and phish from that domain? The other is we need to trust Netgear to run HA infrastructure to support that. (lol)
