The questions I had about my change:

- When should ways not be merged? In this case I merged sections which are continuous with no change in features over them.

- How to mark surfaces which exist but are not accessible to some vehicles (physical restrictions, not "private" roads). e.g. bollards or fences with gates to only allow humans and bicycles to move.

- How should blocks / towers in an apartment complex be named? Is an entire society considered a single apartment? Or does each physical building count as an apartment?
