Status: This is not approved onto Map Features
It's not even a serious proposal
It is a stop-gap pending resolution of the more generic life-cycle tagging. See Comparison of life cycle concepts
A 'dead pub' is a pub which is no longer open. It may be set to re-open after a period of closure for refurbishment.
Fairly useless thing to tag perhaps, but deadpubssociety.org.uk is cataloguing closed down pubs, and could map them within OSM. This explains the fairly esoteric name of the tag. We should change it once we've decided what to do about disused/abandoned features, but in the meantime...
In general... go join in the debate at Comparison of life cycle concepts
But amenity=disused, disused=pub - Seems to be a consensus forming over at question:'How to mark a pub as (permanently) closed?'
