Agreed, though I'm not sure the W3C has much choice. When WHATWG wrested control of HTML from W3C it drove home that browser implementers determine the standard. Given chromium's ~75% market share[1] and Apple's ~18% market share it increasingly seems like the purpose of the W3C is performative, to lend more credibility to what has become a proprietary standard driven by Google and Apple.
