0.3.2 and "custom location server endpoints"

[Sapiosenses]

I assume these must be "MLS/Ichnaea style" servers/endpoints, yes? (Something which I don't think exists yet?)

Or can one use it with OpenCellID, Google, Apple network location services and so on?

The endpoint needs to provide the same /v1/geolocate API that MLS and Google use. This means using the Google endpoint with an appropriate API key there becomes is a viable option, or any other server that either is based on Mozilla's Ichnaea or uses a compatible API like the one mentioned in #2237 (comment)
