we can use the common ";" separator for that
unsigned=key1;key2;key3
for ex unsigned=housenumber;opening_hours

of course it's simpler.
but if every key have it's own logic, tools like streetcomplete need to 
build a long list of several "logic" in stead of being able to make
one logic for all tag.
unsigned=yes was already in use to said that a feature doesn't have a 
name (>1000 uses)
I myself also use it on building to said that a building that should 
have a housenmber doesn't have an housenumber sign
So it's easy to extend to have one-only schema
for all related sign that faild to be found by survey.

Regars,
