I can't remember where I heard this, but someone said once that better performance opens up more, and sometimes new, ways to work with a program. I use GNU Emacs myself, and I basically start it when I boot my laptop and never shut it down, which means that sometimes it has an uptime of months. I will also often not close buffers that I'm working on and can end up with hundreds of buffers in Emacs. Yet, the performance is entirely unaffected (or at least, the impact is below what this human can notice). If Xi is serious about keeping memory usage low, these kinds of patterns of usage that I and many other Emacs users have adopted are going to be viable; on the other hand, in an editor like Atom, one should probably keep as few buffers opened as possible.
