I believe these are the different levels they have at their disposal:

- Remotely delete from everyone's devices (Apple has never used this capability, they say the ability is there in the case of malware)

- Remove from the App Store completely (keeps running if you had it installed, you can back it up to iTunes and reinstall from there, can't download from the store. I think they did this with apps that worked their way around AT&T tethering restrictions back in the day when that was a thing)

- Removed from sale (if you installed it before, you can still re-download it from your App Store purchase history)

I don't think certificate revocation is applicable to app store apps - e.g. I can revoke my own dev distribution certificate and it only kills self-hosted Ad Hoc builds. They may have per-developer app store certs only available internally as well but I think they'd use one of the capabilities above instead
