You’re free to not use example.com. I don’t use it. I use a TLD of my own, and I don’t have any problems since that TLD will never exist in the outer world.

Unless it is .example, .invalid or .localhost and has more than 2 characters, then I need to disappoint you - it may exist (at some point in future) in the outer world.
