Thanks for the updates here! A quick note on deletions: where possible it’s better to keep an existing area, tweak its layout (including splitting or combining it if needed) and change its tagging to reflect its current use; rather than deleting it and creating a new area.

This keeps the editing history, so people can see the evolution of an area over time.
