It's true that you can just use some CSS to make up for the lost HTML feature, but than again you could also rewrite the HTML part.
Forgive me if I'm wrong, but I'm fairly sure that what the OP is trying to say, is that there are plenty of great websites out there, which were developed a long time ago, and for which there is no maintainer to do any work on it. Thus having HTML elements like this dropped, would make the content in a way lost.
Thinking about it some more, users can probably add plugins to add this css automatically, or some browsers might even keep those features in, but still, there will be users that don't know this, I think, resulting in a bad experience.
The "plenty of great websites" were developed long time ago. Having a degree of visual consistency of layout across different browsers was not possible then according to standards.
The content will not be lost. The tags will result in valid elements but the rendering may vary. This has always been a thing to be expected, since legacy elements (pre HTML5) never had uniform rendering and contained quirks.
Should the current/new standard have support for ambiguously rendered quirky elements? Is it even a standard then?
After HTML5 the end result will definitely be the same on most (if not all) layout engines. The standardization as a process requires non-conforming legacy to be dropped.
I may not have expressed myself clearly, but I understood what OP was saying. Never overnight and post, kids.
I was thinking about something like Stylish or the user stylesheet I've been hearing about in Firefox (for their UI IIRC, but still). Inject some global css on older/missing doctypes, and it's probably less than 200 total declarations to handle every older tag. I'd imagine <font> to be the hardest and/or longest, followed by <blink> and <marquee>.
Would be a small extension.
My other point I think I expressed clearly enough, that the loss of presentational markup is not a loss of content in most cases. If the title is in Times New Roman instead of Arial, most of the time it'll just look worse. Unless the content is meta, the presentation is to make things more pleasant to read.
Not sure I'm getting you… An extension to view old pages? This is the worst idea I've heard in a long time. The web is awesome partly because it's backwards compatible.
