Is it really the case that dies/packages are tested and batched
individually?
I mean, you make a good point on reliability/quality, but there are
surely cases where to create a product differential perfectly good (and
known to be good) devices are crippled.
That seems ever less ethically defensible as we move into scarcity.

This is why overclocking used to work - if even a small proportion of the chips tested were good to 25MHz, that was a 25MHz batch, guaranteed good to 25MHz. If you got a "lucky penny" that'd go to 33MHz as per the design spec, then good for you! But it wouldn't be guaranteed to do that.
