You're not wrong, these things are just future e-waste with short-term support, like another commenter mentioned.

There's quite a bit of activity getting the rk3588 working in the mainline kernel. People having current mainline kernel+patches working today, and getting those patches mainstreamed has been making steady progress.

Some places to watch the activity if interested:

My nano Pi R6S (another SBC with RK3588) has dual 2.5GBE and 1GBE, is pretty fast, and has 8GB ram. I expect it to be useful for many years to come.
