Honestly I never understand why so many corporations do exactly that error with their naming schemes. Sony does it for everything too, even though it's gotten better. It's just such a self own marketing wise, even if it makes it easier to differentiate between different variants of the same product.
Samsung does the same for their TVs and appliances but at least they got it right with their phones: there's a "public" model name (for example, the Galaxy S23 Ultra) that is sequential and gives you a good idea of where exactly the phone sits in their line up.
And then a model name that encodes the region specific variant (for example, SM-S912W for my S23U).
Samsung gets it right, but only as long as you stay inside the same "model family". For example, "how does the S23 compare to the A53" isn't a question you can answer by looking at the model numbers alone. They could have used something like "S2X basic", or even keep the A/J/S distinction but make the numbering consistent.
