I look at this in two ways, shooting off the bench and hunting.
If I am working up loads for my gun where pressure may be a problem, I will likely be at the gun club. I should have all of my equipment with me, including a cleaning rod that I can stick down the barrel to remove a stuck case. If I get a case separation, I should have a wire brush of appropriate size to remove it.
If I have properly worked up loads for my rifle, I should not be having any sticky extraction where I would need an ejector notch when hunting. I should have also tested all of my carry rounds in my chamber before going afield.
But let's look on the other side of the coin, let's say I found a load that is just so phenomenal that I don't mind having a stuck case once in a while because it can shoot the flea off a fly's back at 200 yards. Do I make a notch or use another alternative method? Some of the folks here have made the notch. That is their choice. For me, I have another alternative that I have used for many years. I hunt with a fanny pack on. It is great for a rest for prone, has my lunch and water in it, has a first aid kit, has matches, compass, fire starters, whistle, etc....but it also has an old military cleaning rod that comes in about 6 sections. This cleaning rod and the few plastic jags I carry can double as a ram rod for my muzzle loader, can clean a barrel I accidentally stick in the mud, or can poke out a stuck case or remove a separated case.
Your choice.....
