You didn't actually indicate a downside to using xslt, and yes it would fit your use case of a static include for a shared menu, though the better way to do it is to move all of the shared pieces of your site into the template and then each page is just its content. Sort of like using a shared CSS file.

To just do the menu, if your site is xhtml, IIRC you could link to the template, use a <my-menu> in the page, and then the template just gives a rule to expand that to your menu.

the downside to xslt is xslt itself, and lack of maintenance of xslt support in the browser. (browsers only supports xslt 1.0 and it looks like even that may be dropped in the future, making its use not futureproof without server side support)

I'm not sure how xslt itself is a downside. It's a pretty natural template language to use if you already know HTML. You don't need more than 1.0 for your simple use-case. e.g. here's a complete example (tested in Firefox and Chrome):

    <?xml version="1.0" encoding="UTF-8"?>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
      <xsl:output method="html"/>
      <xsl:template match="nav-menu">
        <nav>
          <ul>
            <li><a href="page1.xhtml">Page 1</a></li>
            <li><a href="page2.xhtml">Page 2</a></li>
            <li><a href="contact.xhtml">Contact</a></li>
          </ul>
        </nav>
      </xsl:template>

      <xsl:template match="*">
        <xsl:copy><xsl:apply-templates/></xsl:copy>
      </xsl:template>
    </xsl:stylesheet>
Then here's a page to use it:

    <?xml version="1.0" encoding="UTF-8"?>
    <?xml-stylesheet type="text/xsl" href="templates.xsl"?>
    <html>
      <head>
        <title>Welcome to my page</title>
      </head>
      <body>
        <nav-menu/>
        <h1>Welcome to the page!</h1>
        <p>This is the content</p>
      </body>
    </html>
Anywhere you want more templates, you add another

    <xsl:template match="my-element">
      <!-- HTML for my custom element -->
    </xsl:template>
And now you can use your custom <my-element/> directly in your HTML. You can of course also have attributes and children for your custom elements and do all sorts of things with XSLT if you dip your toes in a little further.

As far as longevity goes, it's lasted 25 years now, so that's something. As far as I know, there are a bunch of government services out there that still use it (which is great! Governments should be making things cheap and simple, not chasing trends), so removing support for it is somewhat infeasible. If it were removed, you could always make a Makefile that runs `xsltproc` on all of your xhtml files to spit out html files, so worst case your back to a build step, but it's the world's easiest build step
