Hi Frans, thanks for validating and spending so much attention on these edits! I'm pretty confident they are indeed ruins, please have a look at how the same area looks like on the most detailed Airbus imagery from 6/29/2023 (I've annotated the same buildings): https://prnt.sc/aOzYg9aVJCOR

I wouldn't rule out the possibility that some of these ruins have been reused for accomodating animals, but they are primarily ruins I believe. Someone would need to confirm this on the ground.
On other areas I've seen these buildings as fresh ruins on Bing, then on later imagery from ESRI they have been overgrown by vegetation. On rare occasions I even saw half of the damaged roof present. Remember, we're mapping a cyclone-struck area with buildings having light roofs that winds can easily take away.

All in all I'd revert your deletions and leave them as ruins, but I'm open to further discussion. 

Thanks for the remark on not connecting roads to area features, note taken.

Best, Peter
