My first reaction, having done a fair bit of XSLT in ancient times, was "I hope not".
After a bit of searching all the examples I could see use JavaScript to glue the HTTP request making part and then invoke the XSLT processor so it looks like the answer is "no".
Sorry, I'm struggling to see the comparison
No, and it wouldn’t be, respectively.
(Also, I don’t think we can go back to XSLT in the same sense that I can’t go back to the moon.)
Does XSLT support making HTTP requests to load new content into an existing page?
