This is the nature of developing for the web: you have to perform cross-browser testing and you have no control over media. It used to be that we had standards for this kind of thing precisely so that huge amounts of effort on ongoing browser testing wasn't necessary. And you have plenty of control over the way this sort of content is presented. Unfortunately all this sort of change and the supportive attitude widely seen in this discussion will do is push sites towards the less flexible and user-friendly options, particularly the sites that didn't previously go for things like DRM. Developing for the web has always been this way. No, it hasn't. "Evergreen" browsers that move the goalposts every few weeks are a relatively recent development, and particularly in the area of media elements and the related controls their approach has been a nightmare from day one. If the dev doesn't have time to be a commercial web developer then they should hire an assistant. How is that attitude going to get more new and useful content onto the web?
