The bolter question is an interesting one. Why do traditional tailhook aircraft bolter? I believe it's because it's quite challenging to fly the approach at 140ish kts using the 'meatball' as your primary visual landing aid (which gives you angular information of your position relative to the glideslope so, by design, it becomes extremely sensitive to errors the closer you get to it). So when you miss all the wires you need a plan B which is to bolt and try again.
SRVL is totally different. The proposal is to touchdown at a fast taxy speed. Are there any emergencies that happen at a fast taxy speed, either on land or on the deck of a carrier, where the standard procedure is to go flying rather than try to stop? Flying the approach at 40-50ish kts, against a new concept of visual landing aids, in an airplane with some state of the art flight controls may make bolters a thing of the past.
So far SRVL looks extremely promising. We could continue to investigate it and look for solutions to its problems. Or we could throw our hands up and give up because dinosaurs in their armchairs don't get it. But if you listen to dinosaurs we wouldn't have the tank, the airplane, carrier aviation or any number of other rather useful things.
