Perhaps we'd want (global and/or local) current + maximum i.e. high water mark + number of times overflow or eviction happened, for a lot of variables that have sizes ("show variables like '%size';" gives an indication). It's the sort of thing we used to do with SHOW STATUS, but indeed a performance_schema table might be more appropriate.
