I felt like I also saw the momentum the OP talks about, and then when I went to try and set up Sway as my window manager in a new Void Linux installation it was a total nightmare. I need some new thing called a "seat manager" that I never needed with X11? And the only options are the bloated elogind (the whole point of Void is to avoid systemd style programs) or the somewhat feature bare seatd, neither of which I could get to work? Pass.
