Integrate/Merge SimpleLogin into Proton Mail's alias system
So users can have unlimited alias with their custom domains and manage their aliases in one place instead of two.

There are several services I've found which have blocked my SimpleLogin email address (GitHub) or straight up deleted my entire account after changing to a SimpleLogin address (Yelp).
Proton's known as a legitimate email service. It's not difficult for services like the above to do a quick MX record lookup and block any addresses that resolve to mx1.simplelogin.co.
Can we please get SimpleLogin integrated fully into Proton, and using Proton's native MX, and the alias system built-into Proton Mail directly?

Simple Login already works with Proton, but a better integration in PM is needed,

They're actually working on it as mentioned here: https://proton.me/blog/proton-mail-calendar-roadmap under "Deeper integration with other Proton services"
