FormerlySerializedAs - Rename dialog doesn't offer adding attribute with ~auto-add~ setting disabled

[Flavelius]

With this combination of settings:

renaming fields doesn't actually offer/ask to add this attribute:

i often rename fields with the intention to drop serialized data, so the combination of not-always-auto-add, but offer-to would be helpful to me if it worked.
In this case i started the rename refactoring on a property that also asked to rename the (serialized) backing field.
