My intent for Animate 2 is to be a more lightweight, memory-efficient and relatively simple alternative to the default animation script, but this came at a cost of removing some of the functionality as you correctly noted
The ideal use-case for Animate 2 are games with a set animation style (as in, predetermined by the game developer), which won’t require the other capabilities the default animation script provides thus will save a bit of memory and hopefully also gain a slight performance improvement by using Animate 2
