Quick answer: almost nothing else makes use of it.  The `methods' package 
is depended on by 27 CRAN packages and most BioC packages.  The OOP 
package is not even on CRAN (although it once was as part of Omegahat).

The official release of R contains packages that are thought to be of high 
quality, actively maintained and useful to a wide range of R users.  And 
those are necessary conditions, not sufficient ones -- an at least 
historic criterion was to fill out coverage of the S Blue and White books
and the sort of statistics covered by MASS (the book).
