(must have been a brain flip :)
Are notches that close to the unit circle even "usefully"
invertible to stable poles?
IMHO. YMMV.

How would you characterize the stability issue of zeros?

Zero on the unit circle in the complex Z-plane
(actually just inside, to be stable even in the
presence of arithmetic/rounding/quantizing type
errors or noise).

What kind of notch filter? Analog? Digital? Software?
I imagine that you are interested in the principle of operation. We
would need to know more about your background to give a meaningful answer

It has a frequency response that is flat then dips down sharply to
attenuate noise in a narrow band of frequencies...
