Being from UPC country I see nothing at all wrong with such violation as for only a 2 inch line, (of course I'm not in IPC code) see no reason a reasonable inspector wouldn't allow it pipes aren't buried in wall or underslab. a good running test would be fine for me as well. I've never been too big on researching why a code has its reasons , why UPC says this and IPC says another. I concentrate on the benefit of compliance versus the hardship or cost if the benefit is so little or non existent but very difficult than no need forcing someone to rework it. good luck its in inspectors hands.
