What, pray tell, would *require* large amounts of absolute addressing?
The number of simple variables in a program is generally modest, and they
tend to be local rather than global.  Arrays and such tend to require
address arithmetic anyway, so there is little penalty in simply parking
a pointer to them in an anonymous simple variable.
