The fact that vim allows composing commands make vim ‘feel’ consistent (and 
which is a good thing) because vim doesn’t have to rely on ad-hoc conventions.
Vim changes the convention to the ‘text object’ concept, which reduces the 
number of keybindings and make different keys have no (or little) relationship 
between each other, which means the key don’t have to satisfy a certain 
condition to feel ‘consistent’.
I’m actually using [composable.el](https://github.com/paldepind/composable.el) 
currently, and also found [objed](https://github.com/clemera/objed) while 
surfing the web yesterday.
Would it be hard to have composable bindings as an emacs default keybinding 
scheme?
