Is it okay to delete old code from -stable kernels?

My message argued for removing 2.5 documentation and retaining the link 
that gives credit to prior contributions.

Since you're obviously being facetious, it's tempting to respond that 
"churn is good because it reduces the average age of the code". But that 
kind of exchange gets us nowhere.

I'd be curious to see an age histogram of the commentary in the source 
code in the mainline kernel repository (or any other long-lived project). 
I wonder if that has ever been measured.
