"""
I'd use read_only when is a field that I will never ever ever update.
Required I will use when I will maybe update it but I don't have to do it with every request.
For example the profile fields, many of them are optional
when I'm updating because sometimes I want to update the name only and not update the email, so I will leave it required=false.
What would be read only would be for example the 'file' field of and image
since I want to make sure that I will never modify it.
