Robert, it was you who suggested to use it if I remember correctly.

How would it be different from what you just proposed?

My suggestion to use the `:properties` slot was not a good one. Looking at the code, this slot is clearly marked as being only for ASDF 2 backwards compatibility (it's hard for me to believe that this is even an issue any more).

Then you can safely un-deprecate it. Unless there is a clear reason to think that using that slot would break existing systems, there's no reason to add another slot.
