I love org-roam. Excited to check this out

Toilet

Mxroute with thunderbird as a client and mail on iOS for mobile.

Unlimited domains and rock solid. Just don’t expect lots of hand holding the company focuses on making email work you have to sort out your own details. That being said they have good documentation.

I think you would be better off using something like org-roam. It’s all text so script can still be used and it can be searched fast with ripgrep. Also org mode has loads of features that a homegrown system will never be able to catch up with

TL;DR: this is a bug fix release with no new features.
