I will also agree that bottoming your forks under hard braking can happen, (I think you think it must happen), but without data logging you do not know if it is happening under 'safe' conditions.(maybe you believe there is no difference between conditions when it happens so safe is irrelevant?) It seems to me there are conditions where you would not want to bottom out your forks for long periods of time (as it puts additional stress on tires). Maybe that too is your point,
So lets assume you have S1000RR track bike.
It is very safe to assume that, typically:
Front fork can bottom out only when you are braking very hard.
You can brake very hard only when you are upright.
If bottom out happens, it is typically a very short time period, and because you are upright, it does not cause any problems.
That is what you can/ should expect from a front fork which has adequate front springs (and typical oil level/ air spring).
If front fork springs are a little bit too soft, and you brake very hard, and front fork bottoms out for longer time period, bike front end starts to squirm.
You do not want to sacrifice you overall front tyre grip by adding compression damping.
You do not want to mess up you sags and bike balance by changing preload.
You do not want to raise front fork oil level, because then front end becomes more non-linear.
Correct options are; brake earlier to be able to use smaller brake force (if you brake earlier you will also lose in lap time), or change stiffer front springs.
You can also assume, when you are trail braking and leaning in:
Front can bottom out, at moderate lean angles, only if you have totally f'd up your sag settings (way too much sag) and spring rates (way too soft springs).
Your brake force (and weight transfer) is getting smaller, so bike does not use that much of compression travel. Centrifugal force does not add compression travel nearly as much as hard braking did.
It is also safe to assume that:
Front or back can bottom out in apex, at full lean angle, only if you have totally f'd up your sag settings (way too much sag) and spring rates (way too soft springs). Centrifugal force does not add compression travel nearly as much as hard braking did, typically about as half as much or less.
Exception to this is long sweeping corners with huge amount of positive track camber. Then centrifugal force plays a major role, and can additionally compress suspension significantly, BUT only if you have maximum lean angle at the same time.
If you are riding long sweeping corners with huge amount of positive track camber, but your bike is perpendicular or so, to track surface, then centrifugal force does not add compression travel nearly as much as hard braking did.
You would need a ridiculous amount of track camber to be able to bottom out your suspension with centrifugal force "only".
Typical crashes are:
Just a little bit too much trail braking before apex.
Just a little bit too much throttle after apex.
I have never seen a crash at or after brake mark when front end bottoms out (momentarily).
I have never seen a crash at or after brake mark when front end bottoms out and starts to squirm.
I have seen multiple crashes at or after brake mark when there has been oil, coolant or water, etc, at braking zone.
And if we mix in typical street bikes (including S1000RR with original suspension) with hydraulic bottom out stoppers, those are bottoming out (hydraulically) typically at every hard brake, no matter how smooth they try to be, and riders do not even know that they are bottoming out.
Yes it is not the same as hard mechanical bottom out, but the situation form tyres point of view is the same: Suspension does not flex, so it is the tyre which must flex.
