Emacs and Vim are basically like that.
They have very vocal and entrenched users so that practically no defaults can be changed lest the single Amiga user will start a huge uproar.
And since they don't really have a BDFL or commercial pressure, they can be super detached even from standards or expectations that appeared 40 years ago.
Neovim was basically a reaction to that, for Vim, where they updated defaults to stuff basically every Unix editor since 2005 has.
