chromium is basically operating system at this point, it lacks kernel and ability to boot independently (added in chromium os), which is both good (from abilities standpoint) and bad (when copy of chromium is bundled with every app that renders webform with text field and button and nothing else)

when it goes about using webapps as desktop apps, native PWA support should be used, it would - in theory at least - lessen most issues electron apps have but will need extra effort and that's why we can't have nice things (like RAM free for other tasks)
