But the precision will be increased almost certainly, to allow for relatively small virtual UTXOs to be realized into regular UTXOs with reasonable fees and amounts for self custody exiting of federations, etc., and to allow for that little bit of extra profit for miners.

yeah, increasing precision is starting to loom on the horizon. but i expect that won't become pressing until next cycle at minimum. when you have 10 sats/dollar there starts to become some issues with pricing common small items. i'd also say that millisats mostly push that into the future another 8 years further. it's possible, even, that lightning protocol may actually defer increasing precision by decades. since the deferment of settlement is the whole point of it.

Makes sense! So judging by our discussion here it'll probably happen sometime between 8 years and 8 decades from now haha!
