For example, one of the people I talk with is doing "Just in Time" rebalancing. If they don't have the outbound liquidity for an HTLC that's profitable for them, then while it's in their interceptor they analyze to see if they can rebalance it in at a better rate to resell.

Beyond my technical abilities by far

It doesn't matter if are 5 or 10 big central nodes moving most of the LN liquidity.
Important is that are other hundreds or thousands of smaller nodes acting as bridges and hops between those big nodes and the rest of the players.
