It would be a bummer IMO to see XSLT abandoned. Its still a really interesting approach to the web and an alternative to today's JS-heavy client rendering.

The idea of being able to ship an XML template with basic logic like for loops alongside the actual XML data source is really unique today. If people cared to use XML at all, that really does cover quite a few use cases that we current reach for JSON + client JS today.
