I have nothing against sixel, of course. But to put things in perspective, Sixel support by itself is not great. Definitely more supported than iterm's, but not universal.

But when developing a new program that wants to output graphics to the terminal, OSC1337 is damn easy (you'll likely not need any new dependency or image handling routines), while for sixel you'd probably need libsixel or write your own encoder.

As a developer, I vastly edge towards iterm's handling. (and to be honest, as a user as well. png encoding is faster too!)
