That's certainly the intent, but as it's written, (by my lay-reading) it appears that the burden of proof would rest upon a single change, and not a sequence of changes -- any one may be innocuous, but their sum may not be. And where a single actor may not run afoul, I can imagine a conspiracy of big players making changes which collectively burden smaller players. I would greatly prefer a consortium or better, an independent standards body.
