building=* + disused=yes.The reason is documented in Deprecated features. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”.
Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the automated edits code of conduct. Any such change will be reverted.
The tag building= is discouraged.
Normally building=* is used to tag construction type, for example building=church is for any building constructed as a church, no matter how it is used currently. building= erases distinction between disused church, disused warehouse, disused barn and so on.
Therefore use an appropriate building=* value, plus disused=yes if the building is disused, but could be put back to use without significant repairs.
Or abandoned=yes (instead of disused=yes) to specify that a building needs major repairs prior to reuse (for example, broken windows, leaking and damaged roof, etc).
building:use=vacant or building:use=none or building:use=no was also proposed as a possible tagging.
In theory disused:building=* could be also used, but it is generally a poor idea as disused building is still a building.
