A deleted property is actually completely deleted?

Because if I add a “Number” property and then delete it, it’s no longer visible or accessible, and it’s not in the trash. Okay.

But if I add a “Number” property again, it’ll be called “Number 2.”

Well, I tested it some more, and the number increments every time I delete and create it.

It seems like you can rename it; there must just be a trace of it somewhere that needs to be cleaned up.
