Exactly this. I have amber to hold my keys safely. Everything else is a portal I can sign into with it. Now you want to be the one unique client to hold my keys while you do other things online exposing a greater attack vector to my keys? No thank you.

I don't keep my data on my server, but I do connect encrypted drives to it!

Single purpose appliances work best.

And I don't want to ever have to paste my nsec anywhere ever again!
