Saxon does this for templates, but I believe, not for all types of functions. In the past I raised this problem and Dr. Michael Kay said that at the time the XSLT WG didn't mandate recognizing and optimizing tail-recursion, because they didn't have a definition for "tail-recursion". Some products are very successful in properly handling tail-recursion. BaseX for example implemented all their operations on sequences with the Finger Tree data structure, which is inherently recursive. They don't have any SO problems as they are using and successfully recognizing tail recursion, as does the modern, intelligent functional-programming world.
