Ahh, yeah, you're right, that makes sense.

AMD has already confirmed that Zen 4 will be on a 5nm node. That's on AMD's roadmap. .
But Zen3 was roadmapped to use 7nm, yet we're now getting rumours it'll use 5nm. Still, if Zen3 APU's use 7nm, the original roadmap would be correct.

I think their GPUs would gain more from snatching an early die shrunk than the CPUs, against their competitors. AMD are far more behind Nvidia than they are Intel in terms of an arms race.
While I agree they'd have to have known about this at the very least a year ago if it's true, I think it's worth noting that these CPU chiplets are tiny compared to GPUs, so would be viable for cheap mass production for CPUs a bit earlier than with larger discrete GPU designs.

Yeah large chips with low yeilds probably aren't the best for ironing out a new fledgling process. Maybe they'll take the chiplet design to GPUs?

I'd expect this gen has already been taped for production. Even if there is virtually no work to be done to migrate to 5nm, there is a tonne of paperwork, testing and bureaucracy involved in these changes, not to mention the testing ect. all of there certifications for meeting different regulations around the world would have to be re-applied for and any copyright protections would have to be updated. I'm not saying that this is not going to happen, just agree that this would have had to be decided a long time ago or add significant delays to the launch. I'd of expected this rumour to have started a while ago too if this was the case.
Maybe will see some refreshed zen 3 on 5nm later on down the road?

Definitely one day but we can't pass those kinda bandwidths through interposers without the heat getting insane yet.
