I think, it should be up to maintainers to decide, but them can be 
removed now and if somebody will need them later, he can bring them back 
without any pain. For now it's just useless memory usage.


I skimmed through priv fields usage and looks like many of them are just 
set, but never used. I guess, some kind of evolution removed all uses of 
them...
