SVGs often render way too big on most websites (see e.g. github and the mozilla docs, see also the screenshot below), providing quite the distraction. Moreover, they are generally non-informative parts of a website (I'm no web developer, but one common use is providing structural rather than contentful information, such as scaleable buttons/ui elements). If someone knows websites that use a lot of non-distracting SVGs removing or altering them is obviously not a good idea.

Other HTML tags that don't add anything to the readability of a page are <input> and <button> tags. I therefore propose to delete them. I'm willing to create a PR, given that I've already tried this for a script in qutebrowser.

Alternatively, SVGs could be scaled to make them less distracting. Looking at the SVG documentation, I suppose one could do something with the width attribute of SVGs. Not really sure how you should infer a good width value for a given SVG and browser window size though (someone who knows something about web development might, however). For reference, I've included a screenshot of the SVG above with a changed width value. To be honest, even though the SVG looks much better, I do not see in what way it enhances readability (at best, it's not distracting, but without much purpose).
