IP Address of Switches on their own VLAN?

[FormBurden]

I have three switches connected to OPNsense, and I'm getting the hang of how to do the VLANs and am creating VLANs and the like. My question is, is there a point in putting the switches in their own VLAN at all? Would it be helpful? Or not really worth it?

The switches are Layer 3 switches. If that matters.

yes
