Is XD Only Available on CC All Apps Plan?

I currently have the Creative Cloud All Apps plan which gives us access to XD as well. I don't use anymore or the apps other than XD and Acrobat Pro so it seems like a waste to continue having the All Apps plan but I need XD to continue operating until I've transition over to a new solution completely since it on maintenance mode. If I downgraded my plan would I still have access to XD or do I HAVE to stay on the all apps?
