And here's a simpler one that seems to avoid views altogether:
   create table lkp(f1 int);   create table t1(f1 int, x int);
   Select        case when Exists(Select * From lkp where lkp.f1 = t1.f1) then            'known'        else
'unknown'        end as status,         sum(x)   from t1   group by 1;
 

It's pretty similar to the sample you gave, but also presents the sort of
operation people may well want to perform.
