Tracking issue to capture all the things we want to make sure get fixed:

• Heuristics engine should have no knowledge of individual space-views classes.
• Space view heuristics don't create 2D space view at paths where there's a 3D space view even if it is needed #4695
• Bad heuristics for objectron #4689
• Move heuristic for viable space view "candidates" to space view class #3079
• Formalize specification/documentation of how transforms interact with heuristics and queries #4655
• DisconnectSpace and TimeSeriesScalar #4465
  • TODO: We decided to keep the name as is, but decided to update the docs to reflect what that it's only about spatial spaces
• Add/remove entities modal doesnt allow adding to a 2D space view #4826
  • see comment, this is expected but there's like more work we want to do on that dialog
• When no heuristics match, still pick a fallback view if possible #3342

Steps towards this goal:

• store applicability of entities per visualizer and update only on change
• centralize spatial topology into a store subscriber
• move "desired space views"-heuristic into a trait method of space view class and have an independent "consolidation" logic piece in the viewport. heuristic results should be availble to the ui regardless (in order to allow showing suggestions)
• execute "desired space views"-heuristic only when necessary -- turns out it's fast enough to skip this!
• Remove the old SpaceInfo everywhere
