Hello Ian
Happy and Prosperous New Year
Thanks for taking time to quickly check our edits and share feedback.

Here are our observations on the findings -
1  iffy change-set which deleted all roads in Carnasa/Carnaza Island in
northern Cebu https://www.openstreetmap.org/changeset/65332385
Roads in this change-set were created by our editor in an island without
any connectivity(Isolated), hence, were deleted during our internal
validation(Quality check).  We were not sure if roads can be created and
left in isolation.  We have such instances in other cities of Indonesia
which could be connected through ferry route, but we are not creating such
roads as we are not clear on the connectivity basis satellite imagery.

2.  Deleting and re-creating a feature, as what happened to the area around
the Magellan Shrine in Lapu-Lapu City -
Existing road was partitioned as it was initially created as a loop.
It infact was not deleted and re-created, but a partition made
might have led Osmcha to represent it as deleted segment

As you rightly mentioned our edits are focused on road geometry - creation
and modification(alignment and attribute corrections of existing data as
appropriate following OSM guidelines)

Kindly suggest if we are missing anything
