Ron Fawcett on probably the 5th ascent also did it without a chock, I have a picture if you don't believe me.

Interesting stance. You're no doubt more familiar with the history of virtually all routes than myself, but didn't Whillans lead this with a peg that he intended to hand place on lead, but when up there found it too strenuous to place so he powered through?
Another story I remember reading about Sentinal Crack was that during a BMC guidebook committee meeting this route was discussed, and despite improvements in the type of gear available there was a motion to upgrade the route. It came down to a vote, and only two or three people actually voted for it to be upgraded. When a show of hand for those who'd actually led the route was made, it was the handful of people who'd led the route that felt it deserved to be upgraded (unfortunately I don't remember where I read this, nor were there deatils of when the ascents of those who'd led it were made in relation to the voting).
Presumably the notion of changing the grade only relates to adjectival grades since the technicallity doesn't change with improvements of gear.
