+Every bit of code requires people to maintain it.

+We view scikit-optimize as mature, stable, and feature-complete. 
+Thus, we don't envision vastly expanded scope or extra functionality.

+Please follow this checklist before asking for a new feature:
+* is the proposed feature in scope and tightly related to sequential
+  model-based optimization of expensive black-box functions,
+* no better Python alternatives exist.
