It's not safe because I could potentially use that information to find a real customer in the DB. It becomes more problematic when working with data from Asian countries where it's possible (even common) for family and/or first names to consist of two or even a single character.

With regards to telemetry I'm aware that it can be disabled. But in my experience that would still result in a veto from the security teams I've worked with.
