I am on UiPath 2022.10 and immediately had an issue when I referenced the UiPath.Robot.Activities.API version 2022.4 due to version conflicts on the executor vs the custom activity package. I could resolve it by finding the UiPath.Robot.Activities.API version 2022.10 but that wasn’t in the main UiPath feed yet and I think I needed to get it from their dev feed, which isnt ideal.
As a result I strongly feel reflection is the correct solution here as it should remain compatible provided they dont make serious changes to the executor runtime and remove the properties the code uses, of course that would also break code without reflection so it really the risk is nothing.
