This allows to pick up runtime configuration changes in the future as well as allowing to simplify the code in future PRs. One possible change is to removeconfigure and to move the remote configuration to just update the singleton instead.

We can add events to activate and deactivate features as soon as updates are incoming that are not handled by a simple property access.

That way most configurations will be changeable at runtime as soon as the remote configuration handles all entries.
