Allow setting position for all tooltips in a group by definine property on <Tooltip.Group />, rather than on each child

This would reduce duplicated code and ease the upgrade path from other tooltip libraries.

No, we will not do that, we've had similar logic in Radio.Group and other group components, it caused a lot of confusion. It is better to separate props – Tooltip.Group is responsible for grouping behavior, Tooltip is responsible for everything else.
