Follow-up from "Fix lint issues": Avoid the need to disable `assignment-from-no-return` for abstract methods

The following discussion from !892 (merged) should be addressed:

  We can probably get rid of the handful of # pylint: disable=assignment-from-no-return by using @abc around the code base. Looking at how many of those exceptions we need, this might well be worthwhile. Definitely a new MR/issue, but still worth noting.

  I don't like requiring disable=assignment-from-no-return for this common pattern. If @abc indeed works for this, shouldn't this be a rather simple improvement and better done as part of this MR?
