This causes a regression in tables (e.g. failing tests here and here)

Mentioned yesterday in internal chat:

but… now our Tables Applications are not listed in the Waffle menu anymore. 🎭

we listen to BeforeTemplateRenderedEvent and add our items then to the navigation, cf https://github.com/nextcloud/tables/blob/main/lib/Listener/BeforeTemplateRenderedListener.php

Is this expected @susnux, and if so what to do about it?

No this is not expected I will fix this. But also its not correct to register in BeforeTemplateRenderedEvent thats far too late and will also cause other problems when apps need to know which entries are available before that.
You should migrate to OCP\Navigation\Events\LoadAdditionalEntriesEvent
