Yeah, "micro" for an editor would be 11 kilo bytes. I bet it's possible to do a half-decent editor in C in 11KB. Antirez's "kilo" (~1000 lines of C) is 36KB when compiled with standard gcc (https://github.com/antirez/kilo).

That said, for many server-type use cases these days, 11MB isn't a huge deal. Still, I wonder if micro could be compiled on / ported to TinyGo and end up a few hundred KB? It looks like TinyGo can produce some pretty small binaries: https://tinygo.org/docs/guides/optimizing-binaries/
