Wow. I hadn't realized so many classes were impacted. I thought there was just a few!

Look good in general. It could be good to write a test that sets the property with 1.0 and 1.1, and that verifies that something (e.g. an ObjectName?) serialized with property=1.0 can be deserialized with property=1.1, and conversely.

That would validate that setting the property no longer has any effect.
