I have good memories of using XSLT. It was a neat idea at the time.
I suppose the world has nearly moved away from XML (for browsers, not yet for folks still enjoying SOAP APIs). And as a result, XSLT has fallen into obscurity.

XSLT is still used on the server back-end for rendering publisher documents (JATS, etc.) and for things like US bills.
Basically it's like a list of everything that was clean-sheet invented like ~ 1996-2007 used XML, then over the course of about 2 years it transitioned, and almost nothing invented after 2009 or so used it. It was like the whole software industry realized what a huge mistake and pivoted to JSON, all at once.
XML is better for modelling mixed content data such as documents ((X)HTML, JATS, DocBook, etc.), images (SVG), or math (MathML). That is why XML is still used in publishing, standards, etc.
For XML, we can add docx/xlsx/pptx/odt/ods/odp to the list.
