You'll see a lot of patches where tools report variables/tables as not 
used, or not really necessary, it's not clear to me how to deal with 
such cases, so I preferred to err on the side of caution.

I honestly don't know if those products are maintained and by whom. I 
personally have no issue removing this variable, but I've been surprised 
to see 'old' products get a kernel upgrade so when in doubt...
