Out-of-bounds access have also been observed in non-Emscripten code, for example [1] [2].
Out-of-bounds reads are very common in code that works with canvas imagedata, because a lot of image-processing algorithms want to examine adjacent pixels, and when you get to the end you end up outside the array. Making out-of-bounds access throw on non-neutered Uint32ClampedArray is a non-starter, imo.
It's still early days for production use of TypedArrays
Uh... No, it's not. They've been shipping for years and people are using them all over, as far as I can tell.
and maybe its not too late to evangelize fixing any major apps that depend upon out-of-bounds accesses or accessed to neutered arrays.
Neutering is more recent, so I can't speak to compat issues for neutered arrays with certainty. I can say with certainty that out-of-bounds reads on Uint8ClampedArray can't change their behavior.
