This was moved over from the original PR, and I copied this change in the wrong place.

There was a problem hiding this comment.
Makes sense to me, and the unsafe code is still sound (as far as I can tell).
Note that SparseSets are no longer present for all registered sparse set components, only those that have been spawned.
Maybe also add a comment to that effect on Storages.sparse_sets?

Good stuff; I think this is a worthwhile cleanup regardless of the final design choice. |

Objective
Progresses #17569. The end goal here is to synchronize component registration. See the other PR for details for the motivation behind that.
For this PR specifically, the objective is to decouple
ComponentsfromStorages. What components are registered etc should have nothing to do with what Storages looks like. Storages should only care about what entity archetypes have been spawned.Solution
Previously, this was used to create sparse sets for relevant components when those components were registered. Now, we do that when the component is inserted/spawned.
This PR proposes doing that in
BundleInfo::new, but there may be a better place.Testing
In theory, this shouldn't have changed any functionality, so no new tests were created. I'm not aware of any examples that make heavy use of sparse set components either.
