I can only speak for myself, but the few times I encountered xslt in the past it was in the context of bulky and verbose SOAP services. The syntax felt off to me (and still do).

I think this was at the time I was learning jquery and using css selector syntax for finding elements, and the difference between that and xpath was pretty stark.

I basically (probably with insufficient knowledge) filed xslt away with vb and tables for formatting as old, complex and soon to be replaced

The syntax felt off to Juniper, too, so they made their own: https://juniper.github.io/libslax/slax-manual.html. Loses homoiconicity to some extent, sure, but outputting XSLT using XSLT never was particularly pleasant.

I can confirm that SLAX is a pleasure to use. Pity it hasn't had adoption outside Juniper to my knowledge.
