Such comments in the kernel tend to be old ones you cannot trust.

And #include removals are not really a common case - sometimes someone
cleans up something specific, but I don't think anyone will remove
#include's of sched.h from random .c files (considering how much
sched.h pulls in the fallout of such #include removals would be many
build breakages) unless someone seriously reorganizes sched.h itself.
