Backward Compatability?

I’ve taken a look at the 2024 SDK and noted that some new objects have been added to the Scenery Editor.
My question is, if I start using these new objects in my scenery files, does that render the scenery unusable in MSFS 2020? In other words, would MSFS 2020 reject the scenery files due to unrecognized objects and I’ll need to maintain a separate scenery for MSFS 2020 and MSFS 2024?
