Those would go into the "shoddy hacks in it for the money" category.
FWIW, my opinion (which reflects a vast portion of the ASCA Aussie world, you know, the original parent club of the Aussie) isn't for you to decide either. You'll be hard pressed to find someone who has been in the breed for a long time who is "ok" with the whole Mini Aussie thing. A lot more respect has been given to those who recognize that what are they working towards producing is no longer an Aussie in the standardized sense and have renamed their dogs accordingly. There are always outliers to the standard; a woman who is well known in the Aussie breed has a Slash V bitch that falls an inch or two under the minimum height, but she calls her what she is--an undersized Aussie. She bred to a typical working male and all the pups in the litter fall within the written ASCA standard. Conversely, there have been those random dogs that exceed the maximum height and weight, but they've not been selected for nor marketed as "Giant Aussies".
Maybe this should go in the "unpopular opinion" thread, but I personally hate size categories in breeds. When you start deviating that drastically from "the norm", you will always end up changing more than just the size--typically temperament. It's been stated countless times over, no one breeds in a vacuum. Change one thing, you'll change something else too. The best programs are the ones that have figured out how to match and balance. So, if you're set on changing a breed, let's say, breeding Shelties to the size of Collies, then you have not just created a category of "Giant Shelties", you have created a new breed. Or poodles. There is nothing about a toy--and most minis--poodle that resembles it's standard counterpart beyond general physical appearance and I feel should be called something else entirely. But phenotype alone does not make a breed. Otherwise, the weim that is built like a dobe could just be called a solid blue dobe. Taking a Groendal, downsizing it and docking it does not make it a Schipperke.
Hell, look at Phalenes. They are basically just a drop-eared category of Papillions, but they've got their own breed.
