I'll take your word for it, given who you are :) 50 lines wasn't really a hard requirement though, just minimal enough that you can sort of get a feel for the absolute basics. like equivalent capabilities to TinyWM. Sway doesn't quite fit that bill as it's more of a fully-fledged wm that you could install on machines you actually use for stuff (I'm running it on this machine for example)

ps. Thanks for creating/maintaining Sway! it's great stuff! ds.
