The idea is the same in that you end up with multiple pubkeys or you re-broadcast with the new key all your past events. But, key compromise always happens at some point and that is a good argument to isolating these points so in a nostr where everybody has multiple pubkeys, people would like to use different subkeys for different points or apps or machines. But as fiatjaf pointed out, this problem is sort of solved with nsec bunker as here, the master key controls how the key can be used and you can give sort of sub keys to different systems without third parties needing to care or know about these sub keys.
