Downside there is you can't tell what's been replied. In a shared mailbox you can move it out and disappears for everyone so you know it's done.

Unlike team members in a small company I actually talk to my SO every day and if it is important she will tell me or forward the mail. There is no problem like CustomerX wrote to Joe last week but he went on vacation and no one knows.

You mean you don’t ask your SO to just do it “async”

My family has addressed this (partially) by using an Auto BCC rule, so that mail sent from the shared address gets BCC'ed to the other partner.
