Ah, Max Staret's comment on that jira issue explains why jsp/jspx could make a difference.
When using a jsp page it's easy to accidentally cause whitespace to be written to the response at the start of the page. And the whitespace output at the start is what is killing PPR. If an xml document has an "<?xml" declaration in it, it must be the first thing - without even whitespace coming first. If whitespace is there first, then it isn't a valid xml document. The jspx format is much more resistant to this as there is a tag (jsp:root) that clearly marks the start of the content. So yes, facelets should also be immune to this problem as it also controls whitespace better.
