Quite uncommon, actually. I have a MT-0 reamer, which I used to
fit fiddle pegs to an Appalachian Dulcimer. The smallest tools which I
have with Morse Taper shanks are MT-1 -- the tailstock taper for my
Compact-5/CNC and my (pretty much retired) Atlas/Craftsman 6" lathe.
The spindle taper on both are MT-2, as is the taper in my drill press.
I do have a few MT-1 shanked drill bits for the tailstock use -- and
some adaptors to turn taps and corresponding drills into MT-1 shanks.

My 12x24" Clausing has a MT-3 tailstock taper and a MT-4-1/2
headstock taper.

Just off the top of my head I cannot recollect anything smaller than
MT2.

As I said -- quite uncommon, though you might find watchmaker's
lathes with that taper. (Most have WW collet tapers instead.)

Enjoy,
DoN.
