I don't think that's the consensus opinion, and suggesting that it is might be misleading to people who are less informed than you are. You already mention Blazor, which would hugely profit from direct DOM access. Various React-like frameworks now exist for various languages that target WebAssembly, all of them would receive performance benefits from not having to go through a JavaScript layer all the time. That's the community side. On the standards side, efforts to enable direct Web IDL bindings are still underway, they just take time. Some things have been postponed because the issues are more complex than originally anticipated. But this will eventually happen.
