No swaps are swaps and splicing is splicing.
Swaps are about liquidity, have to do only when you want to move sats out of a channel, or refill an empty channel, without any resize of the channel.
Splicing is about sizing, making bigger or smaller a channel size, without any moving of sats in/out of that channel.
Think about this:
- swaps: a glass of water that you drink it and refill it. The glass remain the same only the content is changing.
- splicing: a small glass of water, that you change it for a bigger one with the same amount of water in it. Shrinking of a channel doesn't make too much sense, you always want a bigger glass... but yes is possible to shrink a channel too.
ARE 2 DIFFERENT THINGS.
Got it. What happens if you wanna shrink the cup below the water that’s already in it? Do you have to empty the water first?
reply
you can't do that. The shrinking will fail.
The level of water must lower than the new size of the glass.
But what you can do is a swap out into onchain first of the sats from that channel you want to shrink or rebalance with another channel you have, then do the shrinking.
But again, shrinking is quite dumb.

Figured. But do you have to empty the cup completely, or is it enough for the water level to just be below the size we want?
edit: You edited your reply and you already answered my question.
reply
No, no need to empty the channel before doing a splicing in or out.
