That's true, but unless those millsats can be expressed and are "autonomous" on the base layer, it would still be off chain, no?

I can't think of anything preventing wallets from implementing milisat precision in invoices and payments. As you say, it's probably simply for simplicity and UX, since I don't think there is a strong market need for defining milisat amounts in wallets as of today.

We say that #Bitcoin is infinitely divisible. But is that really true?

If msats are the native unit of the Lightning Network, do common Lightning wallet apps like Wallet of Satoshi, Muun, Blue Wallet not support specifying fractional sats in invoices by choice? Just wondering how we make msats usable to end users, and what would cause apps to support msats. Maybe the apps feel there isn’t a need yet given the rough value of 1 sat in the current market? Thought-provoking post, thank you.
