Hi Sam,

I checked in with our Developers about this to confirm I wasn't missing anything, but it's considered standard practice for software, and you'll find other apps use the same file extension for their project files regardless of version—e.g., PowerPoint 2013 and 2016 files are both pptx (or ppt); Captivate 8 and 9 files are cptx; etc. So Storyline and the varying versions using the same type of file set up. 

Hope that helps clarify and if there is anything else I can assist with, please let us know!
