I would do exactly this way and add 
disused=yes.

IMHO mapping closed convenience shop where just
sign/visible interior remain as
shop=convenience + disused=yes
is a mistake as it is no longer a shop.
disused:shop=convenience would make more sense
But for example landuse=quarry that is no
longer used but is still 
a clearly visible object is still a quarry
so in this case landuse=quarry + disused=yes is preferable

Buildings seems to fit the second case,
building tag describes building construction,
not building use.

Building constructed as a church,
now used as a warehouse but still
clearly constructed as a church is building=church

Church building that is now unused
is building=church

Apartments building that is now unused
is building=church.
