Is there anything which prevents this from being implemented here as well?

It's planned, we just need to finish the current features first. We also probably want to make it demo-compatible and speed it up if possible (it's slow on giant levels).

Amazing. This is going to be (another) good year for the development of this port. Quite possibly its best one yet.

And yeah, I've read that in massive slaughter maps people recommend to reduce the amount of stored keyframes and/or increase storing intervals.
