comment Bound states of the $V(x)=\pm \delta'^{(n)}(x)$ potential?
And yet, probability leaking, or non-unitary evolution, could be useful to describe unstable situations. So the deltas produce an interesting family of one-point sinks

On the other extreme, you never need to do derivatives. Just subtract and divide epsilos of the order of planck lenght. Should you tell the students never to do calculus and keeping expanding Newton polynomials (x-e)^n? Note that this includes never to solve Schroedinger equation.

Well, in scattering, and generally in particle theory, you want to be able to argue about asymptotic states not only experimentally but also to define consistently the theory, interaction, etc. Another related thing is when the interaction area has a barrier plus well with some resonances. They can be discrete states inside of the continuum spectra. Regularising the continuum spectra makes a mess because you can not see clearly the resonant state.

Hmm, does scattering count?

(too large for a comment, too half-baked for an answer, sorry by that... but it could be a good start)

@KevinZhou I like your idea. The scaling of the finite well is, er, well understood.
