It's never a bad thing to have more options to choose from when it comes to algs. For most people Ergo-Optimal algs are going to be the ones they want to choose but for others, for example slow turners or those who are looking to focus more on efficiency, move optimal algs are nice to know ( or at least have the options to choose ). An example could be N perm which, at least the one I know, is 21 moves long ( Trigger into J-Perm. Probably not the recommended one but whatever ) vs the optimal alg which is 14. I wouldn't mind learning the optimal alg personally as it doesn't seem that horrible. Another example could be choosing between 3-Style algs and BH algs. Preference is the point basically.
This wasn't made specifically for you. If you don't think it's useful, well, don't use it. Pretty straight forward.
Also,
@Panagiotis Christopoulos, T-Perm is broken. Also good work and thanks for the contribution.
