I would love feedback because I am not sure about the approach.

Himalaya can be enabled at the Home Manager email account level, and it works well because we just need to 1:1 map between an Home Manager email account and a Himalaya account.

But Neverest needs 2 accounts (a left and right) to work. Configuring at the Home Manager email account level was a pain. So instead it is configured at the Neverest account level, where you need to point to a left Home Manager email account name and a right Home Manager email account name.
