I'm a runner who uses HRM 600 + Fenix 8 pro - The watch collects SSL (Step Speed Loss) metric during running, but it is not available in Toybox.AntPlus.RunningDynamicsData (nor via SensorHistory) in the SDK.
Could you please consider exposing SSL and/or SSL% as part of the Running Dynamics API so that data-fields and apps can access it? This would enable richer running-dynamics features and better integration with third-party hardware (e.g., glasses from ActiveLook). I want to be able to do a PR to expose these to Engo eyewear for users who have spent a lot of money adopting Garmin Running Dynamics on Modern watch/HRM.
I don't see it exposed here:

If it is available elsewhere, please let me know.
