While it's great that we can designate our own DNS servers on the routers, instead of just using the ones provided by our ISPs, it would be even better if you could integrate DNS-over-TLS and/or DNS-...
Please add DNSCrypt-Proxy 2 support, which supports the aforementioned DoH protocol, DNSSEC, etc.
I don't really agree with the description above regarding confidentiality/monitoring/etc and our ISP.
What's important is that we are protected from man in the middle attacks. We aren't really gaining any privacy from our ISP (after all, they are getting us from point A to point B, lol). What we are gaining is security.
