For other systems other than Amiga, yes. But Amiga has WHDload which removes the real need for this.
Not totally. Depends on what the "need" is.
If you have a HD and WHDLoad handles everything you need, then fine.
But I'm not sure what the compatibility is for this compared to WHDLoad.
If you have an Amiga 500, to use WHDload, you need a HD and FAST RAM (I believe).
Now, there are other benefits to having those, but they come at a price.
If you can get this for the same or less than the other, it might be worth considering.
Just some food for thought..
