Questions about 'JsonStringEnumConverter' not using namingPolicy when deserializing the object.

if (!Enum.TryParse(enumString, out T value)

Use the obtained string value directly here. But why not use _namingPolicy'?

like:

        internal override T ReadWithQuotes(ref Utf8JsonReader reader)
        {
            string? enumString = reader.GetString();
            
            var v =  _namingPolicy == null ? enumString : FormatEnumValueToString(enumString, encoder);
             
            // Try parsing case sensitive first
            if (!Enum.TryParse(v, out T value)
                && !Enum.TryParse(v, ignoreCase: true, out value))
            {
                ThrowHelper.ThrowJsonException();
            }

            return value;
        }
