It's also common to open these up so that team members can grab a copy of your database. I haven't done that, but I can think of a case in the past few months where a developer had done so. Edit: Now that I think of it and especially with containerized dev environments and VMs, I'd bet it quite common. I'm sure I've opened up a DB or search container more than I needed to just because I couldn't get the damn things to talk. I still would have a firewall, but not everyone does.
