Maybe only marginally. The removal in #28927 clarifies an assumption in the Valhalla code that I was reviewing. And while discussing other cleanups to the markWord code in Valhalla, I noticed that markWord file could probably benefit from a clearer grouping of the existing function. So, this change isn't strictly necessary, but I do think it aids the readability of the file.
