There are some exceptions, but the agriculture machinery industry has actually gotten pretty good at making the names useful, with reasonable consistency across brands. S7 600: 600 tells that it is a class 6 combine, which is a value farmers understand as it pertains to the combine's capacity. For tractors, the John Deere 8R 230 sees 8 indicate a large row-crop frame, and 230 indicates a 230 HP engine. A New Holland T7.180 is, you guessed it, a medium row-crop frame with a 180 HP engine.
It may look like nothing to outsiders, but there is a lot of useful information encoded in there once you know what to look for.
Software doesn't generally encode product attributes into the name the way 230 means 230 horsepower and such, but that's because software doesn't really have things like that to put in the name in the first place. Most software doesn't have specific variants like that, and software that does is almost always differentiated on feature set rather than numbers.
It's not a perfect system. Before the S6x0 was the 9x70STS series, after the 9x60STS series, and the 9x50STS series. You can find a version number in there, albeit not a perfectly sequential one. Although that's nothing new. Windows 3.1 turned 3.11, 95, 98. iOS 17 turned 26. You get the picture.
