Timeline on DOTS milestones

I've been torn a bit recently about whether I should spend my "Unity learnin' time" to diving deeper into DOTS, or uh, finishing my classic Unity Monobehavior Game (which kinda doesn't run very well on mobile at the moment). The hybrid DOTs approach just doesn't seem very appealing to me at the moment. I figured the following elements ought to have a stable API to make an MVP pure DOTS game.

So far tried, and working:
- Got DOTS working with the new InputSystem
- URP seems to work with the HybridRenderer (with certain bugs)
- Movement and basic physics

Needed for a working game:
- Basic Animations system
- More mature API for handling physics collisions and trigger events (I'm assuming the current extremely verbose API and usage of structs will be overhauled??)
- DOTS Audio
- UI?? (without using a hybrid approach)

I could care less about performance at this point. Rather it is more important that the API is stable enough such that a game programmed at time X will still build successfully 1 year down the line when DOTS performance is more optimized.

Roughly how far in the future until the "needed for a working game" items have stable APIs?
