I think it's partly because hedgehog was designed to make async payments work, but I did not consult anyone, I just sort of "did it" as an experiment, in a way that would require wallets to introduce a whole new architecture. Whereas Matt Corrallo has an alternative specification for async payments that is fully backward compatible with existing wallets, and he did years of consultation and background "behind the scenes" work to get consensus/feedback on his approach.

He also has actual people working on it as a serious project. I think every smart and serious dev would/should prefer that kind of work to the kind of experimental "show-and-tell" style of work I do. But that also means they will likely work on implementing his specification rather than mine. I also think my approach is only marginally better than his, and not in a way users would likely notice.
