Benefit to 2 SQL server option?

When I setup my first cyberpanel server, I went with the 2 mariadb option. In retrospect though, is there any benefit to that? Database operations for the panel should be few and far between. Is this just wasting resources?

CyberPanel will continue to work if you have installed two instance version and main MySQL goes down, but normally I install single MySQL instance for myself. There is no other benefit.

kind of wish I would have chosen 1 instance.
