Same for me: I find `gc-live-object-stats' more helpful than `gc-stats'.
But as I said, even if we no longer have it in-core, we should be able
to partially emulate it using guardians et al.

That doesn't seem to be the case, but I need to investigate it further.
Anyway, even if we can have such information, it will be lower-level
than `gc-stats', so not very useful I'm afraid.

Thanks for the pointer!  I'll look into it.

Thanks,
