I know, but normally, we reuse the existing objects to keep the history of it: https://wiki.openstreetmap.org/wiki/Keep_the_history

So, instead of just deleting it, it would've been better to do either one of these things:
- keep it as it is (it's already marked as abandoned and still visible in aerial imagery)
- related to the above: change it from abandoned to destroyed to make it clear it was there before but isn't any more now.
- make it building=construction or construction:building and add a fixme for someone to map the new building outline

With over 10 years of OSM experience, I'd expect you to know that just deleting is not the way to go.
