Satimage is a very longstanding scripting addition, and it is still seeing regular updates, the last one March 2016.
However, I became a bit reluctant when it comes to third-party additions (except with Perl 
).
For example, during the last years I generously made use of Shane Stanley’s ASObjC Runner, mainly as vanilla scripting addition, not so much as ASObjC helper.
With macOS Sierra ASObjC Runner definitely ceased to work. Since I also used it in some longish and complex production scripts (where I – admittedly – almost couldn’t read my own code anymore), the necessary rewrites caused some days of very unpleasant work (in spite of BridgePlus).
Of course, this consideration is completely irrelevant for short-term scripts, and probably not so relevant for simple scripts for personal use.
