Extensions should not a consumer of its own hooks,
just call the code before calling the hook.
In case of EchoGetBundleRules each extension should only handle it's
own event, so this is not a breaking change.
In case if EchoAbortEmailNotification the return false in the hook
handler already aborted further hooks, so this is not a breaking change.

Singletons are bad, amongst other reasons, because they're never reset
in tests. They can therefore occasionally cause test failures if the
cached data stored in one of these singletons becomes stale.
As noted on the task, ideally these two classes shouldn't exist at all,
and core should be responsible for caching the information it deems
expensive to compute.
As a temporary (TM) workaround, make both classes actual services, so
that the setUp/tearDown logic in MediaWikiIntegrationTestCase can
properly reset them between tests.
Dependencies are intentionally not being injected, precisely because
these classes should just be deleted, not improved.

Most notably, CatchableFatalErrorException and the code that throws it
are unused since Ic5712c4ce265b6faabce7a4028b4294fe3c73f18 (in 2016).
