As it stands right now (as of 2024.2.7), the config can contain a location but it isn't used anymore in the code (as far as I can tell).
For multiple locations, you likely only want one location in each instance of Home Assistant.
Enhancement would be that if you add a location in the config, it only loads/instantiates devices that match that location.
low priority compared to modernizing the config flow to be from the GUI. But a good enhancement I think.
