What we would change if we could

Keybindings vs. Keymappings

Make it keymappings, closer to neovim. Can be layered like <leader>abc. Commands don't define their binding, but have an id that a key can be mapped to like

{ key: "ctrl+w", cmd: string | function, description }

Why Currently its keybindings that have an id like message_redo and then a command can use that or define it's own binding. While some keybindings are just used with .match in arbitrary key handlers and there is no info what the key is used for, except the binding id maybe. It also is unknown in which context/scope what binding is active, so a plugin like which-key is nearly impossible to get right.
