Hopefully when RISCv gets there it won’t be so bad.
Now that manufacturers are getting called out for it they tend to follow the support cycle upstream. Now, much of it falls on the chip makers, Qualcomm specifically supports chips for 5 years iirc (and 8 years for their industrial chips).
If the manufacturers can achieve vertical integration, like Apple has, with RISCv I think we’ll see a lot more mainlined support from them.
