Exactly. This proves the point I'm making. No one - even Apple with the best supply chain management in the industry - wants the version scheme you suggest.
Vendors want version numbers to push upgrades to consumers. They don't want to deal with demand forcasting for something with a limited time of life though.
Nobody said that they have to make that versioning public and shout it from the rooftops.
Users do use the informal versioning that I mentioned, because otherwise they wouldn't be able to differentiate the products. I've heard "MacBook Pro 2015" a million times.
And a date <<is>> a version number. It also nicely auto-increments to prove to your customers that the latest thing is better than the old one.
Doodad Pro, 2021 edition. It's not that hard, as I was saying.
The alternative is the garbage that everyone is doing. WH-1000XM3, really?!?
And product lines are speced 12 months in advance.
So you need precise demand prediction all the way along your supply chain for this to work.
