[GitHub] [arrow] pitrou commented on pull request #35149: GH-35141: [C++] Versions of IsNull/IsValid that don't branch on type

   I'm skeptical about this. Did you find any kernels that call `IsNull` or `IsValid`? We have more efficient loop constructs for scanning entire null bitmaps, such as `BitRunReader` and `BitBlockCounter`.
   
   (this is also handled internally by `VisitArraySpanInline`)
