Shame back in the XHTML days XSLT was a spec that could have made website modularity so much cleaner. I once created an early website creation tool that merged separate components using XSLT it was really powerful in the days before javascript was usable without jQuery. However XHTML was dropped in favor of HTML5 and XSLT was pretty much useless after that. Its done well to survive this long I presume it was mainly kept to style XML files.

There's a long discussion about XSLT removal here: https://github.com/whatwg/html/issues/11578#issuecomment-595... (the link is to the comment with this proposal https://github.com/doriantaylor/swet which already is much better than any templating proposal "the platform" is trying to push)
