Problem is that I don't think LPDDR5 comes in any sizes smaller than 1GB, so if they want to stick to the current 512MB spec (and price point), LPDDR4 might be the way to go.
It might be nearer to EOL, but it's not actually EOL and should be fine for 5+ years after any EOL is announced.
Micron have EOLed a bunch of ddr4/lpddr4 parts, but that happens all the time, even to current nodes. There are still plenty of LPDDR4 parts in Micron's catalog [1] that are not EOL. TBH, I'm not exactly sure what the pattern is, maybe it's just parts on older nodes?
Reporters might be overreacting to product change notifications?
Also, it doesn't really matter when the first fabs start EOLing parts, it only matters when the last fab closes. And LPDDR4 might be a long-lived part, simply because China have opened a DDR4/LPDDR4 fab. Which might actually cause non-Chinese fabs to shut down DDR4/LPDDR4 early to focus on nodes with less competition.
