I am very confused as to what is being argued here. Yes, when people got bent while working in deep pressurized mines and bridge-building caissons, they were indeed in pain. That was certainly a clue. When Chris Rouse reached the surface after his dive, he died there within about a minute. That was certainly a clue. So, yes, if you get bent that badly on a dive, you will know it pretty quickly.
A lot of people would prefer a warning before that happens, and there is no perceptible bodily reaction prior to the symptoms once you are bent.
There is actually a body of evidence that is contrary to that statement. Some people do have what's considered by many a mild "prodrome". This workshop provides a few examples of the diagnostic quandry of "mild DCI". https://www.diversalertnetwork.org/files/RemoteWrkshpFinal05.pdf
And Andy provides a literature review on his ScubaTech Phillipines website along these lines as well. Subclinical DCS, Decompression Stress and Post-Dive Fatigue %
