Seems quite probable that this is more or less how and especially why it's set up like this.
Not quite convinced its the most efficient way, TBH.

Why is your 1PW extension is 700MB in RAM? Others posted here showing 1PW with the assistant running is around 170MB IIRC
1Password X is what became the extension for 1Password 8 and it’s been around since 2017. You always needed the subscription to use it. I was beta testing when it 1st came out and it’s great because I was able to 1Password on Linux at the time. Now on my Mac and Windows I do use it along side with the desktop app, on my work computer and my Linux computer, I use just the extension.
I do not understand your setup. There are 3 things: App, the mini assistant, and the browser extension for browser autofill. Has this setup been changed? There is no place for 1password X in the current implementation.
