> with a perfectly normal text editor That's... a bit unfair characterization of Emacs. It is built for extensibility, built as a development platform for Elisp packages - and that's not how most editors are designed and coded. Anyway, it's probably completely possible to adopt many or most proposed features into Emacs but it could be prohibitively hard to adopt them into some other editors.
