More live activities on Apple Watch?

I only recently realized, since it didn’t seem to me to be pretty evident, that specifically cycling workouts from Apple Watch can be mirrored onto the iPhone as a Live Activity.

Is this available for any other workouts? I often do a lot of steady-state cardio using machines at the gym, and having a live, static screen to display my metrics separate from having to raise my wrist every few seconds would be very helpful. However, judging by this Support page, that’s just not a thing.

I feel like having any workout type being integrated with this feature would be a simple yet powerful feature for those trying to use Apple Fitness to its full potential.
