Thanks for the heads-up, I didn't know wuffs had a WebP decoder. Just benchmarked it (b2e6da3), and wpd is about 2-3x faster on lossy stills, 5-7x faster on lossy with alpha, and 7-8x faster on lossless on my M5 Pro (even single-threaded).
Also, wuffs is not bit-identical to libwebp, and animated WebP is completely unsupported, so I'm not sure it is a real option for WebP decoding.
