This stuff is very new and still in beta. Even once a stable release is made, I suspect it will be some months before all the various kinks have been worked out. After that, we can potentially look at moving some of the FSRS options out of the advanced section, but I do not think the time to do so is now.
It uses the same search as for computing weights.
This is a big update, and it’s going to break some stuff. Addons that were using pointVersion() instead of doing their own version parsing will be unaffected.
