Then maybe it worth to consider more general API advancement at once?
Here's my wish list:
1. Choose subtree function as an alternative for penalty
2. Bulk load support
3. Better split framework: now many extensions peek two seeds and
spread split candidates among them, some with subtle but noisy
mistakes
4. Better way of key compares (this thread, actually)
5. Split in many portions
