No_sql vs the Stepping API

Consider the definition of a stepping bytecode: append_while_match. In graph languge, this is collecting from a word look up table. In @ this is Gout@"word",Dictionary. What happened to the Sql? Gone? No, underneath the Qson machine used the appropriate bytecode for the machine it compiled with. Sql developers made sure that they have great steppers, other developers will compete with different implementations of the stepping API. But Sqlite3 has the best stepper in the business right now. So underneath is the insert into Gout select key,link,1 from g2 where g1.key = g2.key; Why not?
