I like this implementation but on second view it looks like Osmosis does do a swap before provision rather than only providing to one side. Additionally looks like Wynd did that too. The behaviour of single provision and only providing to one side is similar to Uniswap. Do we want maybe to add an option to do the swap? https://medium.com/osmosis-community-updates/single-asset-lp-67fb48abce53

Good point. Let's explore doing it this way.
