I expect the predominant use pattern for editors (in a console) is to be fired up to quickly to edit a file, save and exit, e.g. to commit files in source control. Longer term activity has moved out to the desktop and editors / IDEs running there - the likes of Eclipse, Notepad++, Sublime Text, Gedit etc.
And since that was an issue with Emacs around 20 years ago, emacsclient exists, to load the file into an already running instance of Emacs, but otherwise act as a console editor is expected to (hanging around until the edit is finished). But on any modern machine, Emacs starts pretty much instantly with a warm cache, and in a couple of seconds at most with a cold cache, so starting Emacs for a quick edit really isn't the issue you think it is any more.
