Yes, I want to make/keep it possible that application developers can be unaware of partitions.  I believe that's why David-san, Alvaro-san, and you have made great efforts to improve partitioning performance.  So, I'm +1 for what Hou-san is trying to achieve.

Is there something you're concerned about?  The amount and/or complexity of added code?
