A centered playhead would be nice. There's needs for the existing sweeping playhead as well. It would be nice to make good use of both for different needs. One can hope we see that with Studio One in the not too distant future.
As a workaround for all tracks ripple edit, simply set the loop marker where you want to drop out sections along the timeline. Then simply right click to delete time along the timeline. This instantly deletes and closes the gap on all tracks, so this effectively works just as fast.
Yes definitely need both types of playhead behaviour.
The workaround you mention is one I’ve used and is very well implemented in Studio One.
