Indeed. I was trying to humorously reference the author's staunch refusal to remove `xterm` from the TERM identifier, knowing full well that many programs simply look for `^xterm` when determining if the terminal is compatible. As you eluded to with 'NIH', the same author refused to implement Sixel in Kitty because it is "inferior" to Kitty's image implementation.
What does "NIH" mean in this context?
Kitty developer decided to go with a custom image display protocol instead of going with sixel.
