Hey!
Thank you for fixing my issue!
The fix looks quite complicated and tests are hard for me to follow.
The main concern is about changing values with non-default.
You can find my thoughts and suggestions below.

upgrade logic were updated after review:

updateAttributesOnlyOnValueChange will be true by default(if value is "null" or missing in the configuration)
