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.
