Ah I see, thank you very much for your answer! It did make some things more clear.
There is another thing I'm intrigued to hear about, and that's the speed change concept of the extension. It was mention that it can speed things up as well, does that mean that the regular animation speed can go beyond it's 100% cap, or is it solely making already existing things work easier?
Yes, you can have things run above 100% speed.
Basically Fusion already let you set the Movement Timer in the each Frame properties, they are 60 (to match 60fps speed) by default.
The extension allows you to not only set that during gameplay but also get the deltatime so you can integrate more stuff to it.
Here's a video of an engine I've made using the extension, and you can see I testing the time speed.
