requestHandler and postNavigationHooks seem redundant #1633

Which package is the feature request for? If unsure which one to select, leave blank

Feature

Providing requestHandler is required but IMO it is redundant with what postNavigationHooks are there for. The semantics are IMO also rather confusing, as the function does not handle network requests but rather navigation.

Replace requestHandler(ctx) with new navigationHandler(ctx, gotoOptions) and fix confusing request-handling semantic when navigation-handling is meant.

Thoughts? What can you do in a user defined requestHandler that you cannot do in user defined post navigation hooks?

Motivation

Fix #1631.
Reduce confusion.
