True, long run app support is still pretty shaky. But I think it's the best "middle" solution since running a full bitcoin node is gonna be a hefty lift for most people, and custodial lightning has a lot of rugging / regulatory risk.

And yeah, the time investment and cost for routing is mostly related to rebalancing and liquidity. I also think you need to make pretty big channels in order to route profitably... that's a lot of sats you put at risk.
