Please add more privacy preserving DNS over HTTPS resolver options by default

I added some privacy preserving DNS servers that offer DoH capabilities to my network.trr.resolvers like given below:

[
{ "name": "Cloudflare", "url": "https://mozilla.cloudflare-dns.com/dns-query" },
{ "name": "Quad9", "url": "https://dns.quad9.net/dns-query" },
{"name": "AdGuard Default", "url": "https://dns.adguard.com/dns-query"},
{ "name": "AdGuard Family Protection", "url": "https://dns-family.adguard.com/dns-query"},
{"name": "Google", "url": "https://dns.google/dns-query"},
{"name": "CleanBrowsing", "url": "https://doh.cleanbrowsing.org/doh/family-filter"},
{"name": "PowerDNS", "url": "https://doh.powerdns.org"},
{"name": "SecureDNS.eu", "url": "https://doh.securedns.eu/dns-query"},
{"name": "DNSWarden AdBlocking", "url": "https://doh.dnswarden.com/adblock"},
{"name": "Foundation for Applied Privacy", "url": "https://doh.appliedprivacy.net/query"},
{"name": "BlahDNS Germany", "url": "https://doh-de.blahdns.com/dns-query"},
{"name": "BlahDNS Japan", "url": "https://doh-jp.blahdns.com/dns-query"}
]

Many inclusions here might be considered controversial or dubious. But at the very least, Thunderbird should include DNS entries that claim to block tracking pixels like Adguard.

There's a huge list provided by curl in its github page to choose from: https://github.com/curl/curl/wiki/DNS-over-HTTPS

To be clear, I'm not asking for the default to be changed. Only for options to be included so I can ask friends to choose a sane one from the list
