Because of "going back" always behaving like "go to parent", all paths need to start with / in order to work well with the component's pattern matching logic

Sounds like we can remove the experimental callout now.

I was planning on removing those experimental callouts and Storybook tags once we also export the component without the experimental prefix (in a follow-up PR)

Should we just suggest goBack()? For someone attempting to use goToParent, it's not immediately clear in their IDE that goBack is the recommended alternative.

The NavigatorBackButton doesn't have a goBack prop, since "going back" was already the default behavior. The goToParent prop was changing that behaviour, but now that the default behaviour of "going back" is the same as "going to parent", that prop basically became a no-op and can just be omitted.

Actually thanks to your comment, I realised that this deprecation was not necessary because that was a code path that could not be hit anymore. I just removed the code instead: da79e35
This can be done because its usage was actually only internal to the component

What?
As discussed in #60927 , this PR introduces a few simplifications (and deprecations) to the
Navigatorcomponent.Why?
We're simplifying the component's API ahead of promoting to stable.
How?
NavigatorToParentButton,NavigatorBackButton.goToParentanduseNavigator().goToParent()as deprecateduseNavigator().goBack()andNavigatorBackButtonwill navigate to the parent screen, instead of navigating to whatever screen was visited prior to the current one (according to the expected URL-basedpathassigned to screens)Questions
goToParentandNavigatorToParentButton?replaceoption make any sense with "go to parent"-only backwards navigation?Next steps
Testing Instructions
Navigatorshould continue to behave as ontrunkin Storybook and in the block editor
