Trusted favicon domains database

[mKoonrad]

Hello
I recognized in my way your API for viewing sender images in Proton Mail packages/shared/lib/api/images.ts

I discovered that you only serve some “trusted domains” favicons. Is there any option to make this list public? Or can you provide any option to suggest missing popular and trusted domains? It's very helpful UX feature, but I can't see many domains with this image.

Also curious about this! I believe it's also related to #408 and may explain why there are a good number of logins in Proton Pass that are missing favicons.

I imagine there are security reasons why there is an allowlist, but it would be nice if that list were relaxed a little bit to support more domains. Or perhaps reverse it to blocklist of known malicious urls.
