- Event-based session invalidation requires knowledge about the
dependents of a `KtModule`. This is because, when the session for a
module is invalidated, all sessions for modules which depend on that
module, directly or indirectly, must also be invalidated.
- Note that the approach with modification trackers relied on module
dependencies. Events have an opposite flow of information compared to
modification trackers: Modification trackers request whether a change
occurred, while events publish that a change occurred. Thus, the
modules which need to be incorporated into the invalidation dynamic
are also flipped: dependents instead of dependencies.
- `KotlinModuleDependentsProvider` is designed to work generally. It can
be used for purposes beyond session invalidation.
