Did Anthropic restrict kernel-writing after hillclimbing it to slow rivals?

teortaxesTex offers a take: Anthropic restricted the kernel-writing capability only after hillclimbing it to superhuman levels, possibly to slow competitors' R&D.

His assessment: the frontier labs are hurt more (their models are weaker at this), while open source — though weaker still — has far more kernel engineers than GPUs to compensate. Industry speculation, not officially confirmed.
