I still use Twig templates for a couple of my simple marketing websites, backed by about 100 lines of PHP to make it work. Simple enough that my non-programmer friend can edit it, powerful enough that... well it's not that powerful but it can do templates, which is all I want out of it. And I can still fall back to PHP if I do need to sprinkle some server-side magic in it. Stable, no maintenance, just keeps working and working, over a decade later.
