Multi-programming provides best hardware resource utilization. When one process gets completed then another process is scheduled that was waiting in the queue. I don't see any disadvantage of multi-programming.

One small disadvantage I see is - context switching which is a costly and non-productive operation. Sometimes it can also happen context switching is more time consuming then the time saved by multiprogramming.
If I am correct, your statements are somewhat related to multitasking not the multi-programming. Context switching is related to multitasking.
Good catch
