I don't have a particular need of nanosecond granularity timestamps for WebGPU- there are other parts of the web stack where I could really use better time measurement- but I understand the security concern and it's far better to be safe than sorry.
But they quote two wildly different granularities in the same article, within a paragraph of each other...
