I checked 3 or 4 spindles and none of these holes went anyplace. There is metal in front of all of them. I thought maybe for oiling the bottom bushing but they seem to be holes to no where
Although I'm not a T owner I did stay at a Holiday Inn last night! Seriously, to me it looks like a centering point for machining the bearing surfaces on the spindle during manufacturing.
I believe it's a centering hole for its manufacture: machining the spindle and cutting the threads.
That is most likely the hole for the lathe center that was used to machine the rough forging.
See how it is lined up with the end of the spindle where the threads are.
Wasn't it to center it on a lathe for threading?

But it was sooooo close !
