My favourite company for naming and versioning products has to be Creality. Their philosophy is: If it sells, keep selling it, and proliferate more, slightly varied models of it. Make no attempt to prune the product tree, and if our competitors have a popular product, take one of ours and rename it similarly, and then continue the version updating from there. Their most popular machine, the Ender-3, has these versions alone: Ender 3 V3 Plus Ender 3 V3 Ender 3 V3 SE Ender 3 V3 KE Ender 3 S1 Ender 3 S1 Pro Ender 3 S1 Plus Ender 3 V2 Neo Ender 3 Max Neo Ender 3 Neo Ender 3 Ender 3 Pro Ender 3 V2 Ender 3 Max

This is not exhaustive. Wild. Their PCBs, liberally scattered among the models, use SemVer like numbering, like 4.2.1, but with no obvious pattern, could include 8-bit or 32-bit processors, basic or advanced motor drivers... Basically anything goes.
