That is a bit different to "users are using but less and less". Personally 
I would not mind leaving code in the kernel as long as it is used, but
it would be great if we had some rule that a file/driver which did
not compile for X releases (pick a preferred number for X - two years 
worth of releases ?) can be removed.
