Whether it is "significantly easier" to manage these types of problems and at what cost remains to be seen.

I do not understand you comment about "confirmation bias" as did not make a quantitative prediction that could have bias.

The fix was outside of any Rust unsafe blocks. Which confused a lot of Rust developers on Reddit and elsewhere. Since fans of Rust have often repeated that only unsafe blocks have to be checked. Despite the Rustonomicon clearly spelling out that much more than the unsafe blocks might need to be checked in order to avoid UB.
