vss.xml is a semantic identification file for your website.
It defines who you are, what your site is about, and which pages represent your core content.
It is not a sitemap and not an SEO tool.
vss.xml is used to understand and evaluate websites fairly, based on real content and visitors.
Without vss.xml, a website cannot be registered or monitored.
