Poor key binding support is still a problem despite the optimistic quote (and might last for one more generation given the snail speed of progress). For example, the kitty protocol isn't "comprehensive" despite its dev's claims: it doesn't support left vs right modifiers and also some non-standard modifiers that are used to circumvent this limitation (only hyper)
> At least I indeed saw no such issue using helix in wezterm for example.
I think helix still doesn't support even the full kitty protocol, e.g., the Windows key.
And I do see these issues since I'm using richer keybindings to make input more ergonomic.
