Yeah, but what format will you get? There has been a format wars in this space going on for years. Multipart-HTML has made a reappearance in recent versions of Blink, but won’t open in Safari or Firefox. Safari has its own binary-XML M/HTML-inspired “Web Archive” format that won’t open in any other browser. Firefox saves the HTML file together with a directory of most but not all the resources required to render a page. This last format is similar to Blink’s default non-M/HTML format, but makes different decisions about what parts of the document to save. Print to PDF is a good and accessible method for archiving pages that preserves formatting. Web developers can spend two minutes out of every year to add a @media (print) { some-miniscule-layout-fixes-to-optimize-for-print } and their users will get a good-enough archival format when they need it.
