Not sure most people are aware of the benefits (I'm not).
My understanding is that the commitment transaction is basically the transactions you are "passing around" with the other side of a lightning channel, your updates to the "bar tab". There is an issue that if these are too old, when you try to force close a channel, it fails because the fee to the miner is too low, so we need a mechanism for either side to bump the fee.
If this is correct, can you complete it with why is it important to support zero fee commitments and what exactly do they solve? (Or share a link 🙂)
