We just learned through SteamDeck that it is already possible for a handheld device to house a downgraded RDNA2/Zen2 alongside an NVMe SSD at a fairly decent price and battery life. In other words, PS5's architecture is likely "scalable" as I was speculating/hoping it would be back in early 2018.

Downgrading silicon to hit various formfactors, TDP and power consumption targets has been a thing for decades.

So I wasn't really surprised.
In-fact I argued Nintendo could have gone down the same path by opting for AMD mobile hardware before Tegra got confirmed by Nintendo themselves.

Was the Switch form factor plausible at that time with x86?

I would have done the same thing Nintendo did, and that is to continue evolving their portable hardware with ARM.
"ARM chips are designed for low power draw, flexibility, low cost and low heat with good performance"

And adding this link, if this goes down to a x86 vs ARM, or CISC vs RISC:

With Apple betting on ARM, and the SteamDeck with AMD, it's going to make the portable space exciting:
