The way this motion is written, NuLagoon is responsible for ensuring liquidity on a supported pair, whether it’s their liquidity or not. Clearly, ALix is a great way to measure this. However, I feel like if ALix is mentioned specifically it will become the end goal rather than the actual exchanges.
As an extreme example, say ALix is down or compromised. What happens to the NuLagoon contract? Do I have to put in clauses about how to determine if ALix is compromised or not? Instead, we can just say what we want (liquidity on actual exchanges within 1.5% of the price feed) and let the usage of tools like ALix be implied.
