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.

Yeah, I am being lazy. I need to see what is being done with the current properties slot and whether it can be taken over, or if it is doing some weird classic ASDF thing that I need to stay away from.

I will post more once I have groveled over the code.
