To my knowledge, what is being taught, in perfect accordance with
Heisenber's teachings is that the electron is not localized until
the wave function collapses. So, when in motion, it is definitely
considered in the Copenhagen school view of QM as being spread out.


Stationary states aren't subject to uncertainty.

Wrong. Why do you think so???


The
parameters of an electron in a stationary state can be
measured with precision.

Only the energy can (in principle) be measured with precision in
stationary states. Both position and momentum are "uncertain".


Via multiple observations
of identically prepared systems, one can measure the
distribution of degenerate states, that is, states of equal
energy and angular momentum, to unlimited accuracy.

It's not clear to me what you mean by "measure the distribution of
degenerate states".

Additionally, AFAIK, "degenerate states" means only that the energies
are equal. The states can have different angular momenta. E.g. the
states |200 and |210 of the hydrogen atom (using a notation |nlm for
the states here) are degenerate, although the l is different.
