It's not directly a security problem as in your computer is gonna get hacked, but it can ruin your opsec if you don't want people to realize that you're the person controlling a specific key.

I would hope if you're doing serious opsec you're using ephemeral keys or isolated virtual environments for various endeavors.

Yep. I would also hope if you're 'doing opsec' you would know how your tools work.
