[Question] em.isActive(entityId)

@junkdog implementing the testcases for the debugger I’m running into some engine behavior I can’t find any documentation on.

After entity deleteFromWorld is issued, until deletion is finalized by the batchprocessor, em.isActive(entityId) returns true. Does this mean all interactions with the entity (except for deletion) are considered legal? Or should the method return false right after deleteFromWorld?

I ask since it seems like an artifact from how the engine works and not so much intended (see EntityTransmuter#isValid for example, it will block transmutations which will block componentmappers from triggering create/delete). But for some reason it treats deleted-finalized entities differently and throw an exception.

Edit: DelayedComponentRemoval suggests component read is intended for that group until all subscriptions have been notified.
