Our internal backlog for the engine and editor (ie not the same as this: GitHub · Where software is built) contains 844 open and 365 closed issues. There will always be more open issues than we have time to fix, and we will prioritze issues that are blockers or often requested by our users. This issue is not in any of those categories.
Yes it is. It is a feature request. Not a bug.
Contrary to popular belief nothing in game engine development is trivial. A lot of care has to go into every line of code added. Are there side effects? Will it have a performance impact? Will it break things in existing projects?
One problem is that two game objects can’t have the same id. If we use the factory component id to build the sequential ids of spawned game objects we may run into situations where two factories with the same component id will generate game objects with the same id.
