Look, to me, "drop-in replacement" means something very specific that even a naive academic can understand. It means I can switch "using MongoDB" to "using TokuMX" at the top of my code, change *nothing* else, and have everything work. I might speculate, from my ivory tower, that this property is relevant when trying to get customers to switch to your product.
