That's what the canvas tag and WebGL are for; yes, you use DOM APIs to gain access, but the APIs for using them are essentially bypassing the complexity of the full DOM; canvas is a raster image, that's all, no internal interactions with CSS or the rest of the DOM, the DOM just positions the square and you draw into it directly.
As for "nobody is really going to develop new games inside a web browser", what do you think all the free to play stuff on Facebook is? Or every old Flash game? WebAssembly just means that you can write the same games in whatever Emscripten supported language you like, then cross-compile, instead of using Flash, hand-coding JS, etc. And that's before we get into playing abandonware games; cross-compile an emulator like DOSBox to WebAssembly, and you can serve the original game files directly, only the emulator needs to be cross-compiled. Archive.org has already done that for hundreds of games using asm.js

Setting the bar real high there, ain'tcha?
Funny, for all those "crazy Government mileage requirements", I find that the cost of new cars has generally risen at slower than the rate of inflation, even as they offer more features, better reliability, and (thanks to said mileage requirements) lower fuel costs.
Case example: My parents bought a Geo Prizm LSi (also marketed as the Toyota Corolla) back in 1990. At the time, it cost ~$12.3K. It was much smaller than the current Toyota Corolla, the electrical system sucked (adjusting the power windows dimmed the headlights and radio), etc. The LSi add-on features (power windows) are all standard now, the MPG has gone from 21-22/26-28 MPG city/highway under the old system (that rated all cars better than what you'd actually get), to 27-29/36-38 MPG under the new, more realistic rating system (and remember, the car is actually bigger now than it was), which reduces your fuel costs by a third or so. Yes, the cost is up, between $19.5K and $22K for most models (remember, the 2015 low end model is still better on features than the top end model of 1990). But that $12.3K from 1990 is ~$22.4K in 2015 dollars (according to U.S. Inflation Calculator). So the price actually dropped in inflation adjusted dollars, while the car got bigger, more efficient, and got more "luxury" features.
Remind me how big bad government mileage requirements are making cars so expensive?
Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court.
If you levy war against the U.S., it doesn't matter if the U.S. has declared war against you. And you don't actually have to be making war, that's just one way of being labelled a traitor.
