Hi @AFrederick3,
There are downsides and upsides to this new behavior. The previous behavior, for example, blocked using properties for multiple forms that were not supposed to show all options but only a selection. Adding a value always meant having to check all forms where it was not supposed to show up.
I agree however that users should have more control and the best option, in my opinion, would simply be a pop-up, asking whether a newly added option should be added to all forms or not – similar to list changes prompting a pop up asking the user how this change should affect workflows referencing the lists.
