The cause for this change is that TPU says we want to print with brim but CPE wants to print with raft. In those cases the resolve function would choose the raft because that's safer. However if the default extruder happens to be the TPU one you then get a raft made of TPU which is flexible. That defeats the purpose of the raft, and causes the raft to warp, clog on the nozzle, destroy the world, etc. So there, I saved the world once more.
it shouldn't have a child setting because that child is not the underlying setting used by the engine.
Parent settings are frontend-only settings which are merely used to let the user edit multiple leaf settings at once.
This was found by the materials team to be a better value. All UM3 profiles have 20 now. I've left the third-party machines intact which override the prime tower size but those that didn't override the prime tower size have their prime tower size altered as well.
It is actually being set per extruder right now, since this is where the definition gets its extruder number from. If the setting is not settable per extruder, the ExtruderStack skips the setting entirely and defers to the global stack, which doesn't have the setting and so None is returned. This was giving errors.
Contributes to issue CURA-3772.
All of the profiles currently in Cura that set the gradual infill steps also set the step height (to 3 to 5 layer heights). I'd have chosen 4 layer heights as default based on that, but our material experts say that 1.5mm is about right for most models.

These settings inherently have to do with multiple features and
so we should find a value function which depends on
settings from the extruder trains corresponding to those features (wall, skin, infill).
However, we haven't found those functions yet and we have to do research.
Once we have found the formula these settings shouldn't depend on a single extruder any more
and so we should remove the limit_to_extruder.
