It doesn't look nice with sidebar, that's why its not there. If you want to create a PR, then make it optional to enable footer (using frontmatter or some theme config) on doc pages.

Yeah honestly it would be good, especially if we need to display some must-have copyright info or something else.

Here's how I solved it
in .vitepress\theme\style.css add this

footer.VPFooter {
    display: block !important;
}
