The .17 Hornet quite honestly just gives us the last picket in the sensible .17-cal fence. We now have the .17 M2, the .17 HMR, the .17 Hornet, the .17 Fireball, and the original .17 Rem. The last one of those (and the first one introduced commercially) is arguably overbore for that bore size, based on its propensity to foul bores and its often quirky pressure curves. Nothing bigger makes any sense.
The only other missing case size that could go commercial would be the .17 Bee, and I doubt that will ever happen.
