To @Lyn Alden ‘s original point, have you tried a large payment like that on your own Lightning infrastructure? “Strong doubts” sound like you have not. That dude that claimed the bounty has not worked on figuring it out and trying it. He’s just fortunate that Strike exists and made it easy. FYI I routinely send and receive payments larger than that over lightning in a non-custodial way. It works well and gives me quite a few unique benefits. Not saying that as a flex, but trying to offer a data point rather than an assumption. 😃
