The edit was quite extensive and done in OsmInEdit, meaning I had to redraw most of the buildings, update the indoor map, and then adjust the surrounding features. If something was deleted, it was purely accidental. In this case, there really wasn’t a need to comment; if something’s missing, it can just be added back. A comment would only make sense if deletion was the actual intention of the edit, which it wasn’t. On that note I’ve also noticed that some features have been deleted multiple times in the past, so I just restored and corrected things rather than commenting on every single change unnecessarily. It’s also pretty common for features to get deleted, whether by accident or sometimes even vandalism.
