In short, because there are too many problems with starting the eventloop by default without stating so and requiring the user to know what's going on. I don't know all the reasons, but one example that comes to my mind is that if you use Vibe.d for a simple curl-like script, you might be wondering why it never exits. Also you mention `static this` in your title, but usually `shared static this` should be used. Oh. I've been using "static this". Noted. There are also other concerns, e.g. the @safe-ty of the eventloop is never checked when you use the default main method. Hence, in 2014 VibeDefaultMain was introduced to move away VibeCustomMain (which required the user to take explicit action when the eventloop shouldn't run). Nowadays, a user neds to choose whether to use the default main loop (versions "VibeDefaultMain") or call runEventLoop/runApplication, but "VibeDefaultMain" with shared static this is deprecated. static this seemed clean though :)

Like:
#!/usr/bin/env dub
/+ dub.sdl:
name "hello_vibed"
dependency "vibe-d" version="~>0.8.0"
+/
import vibe.d;
void main()
{
auto settings = new HTTPServerSettings;
settings.port = 8080;
listenHTTP(settings, (req, res) { res.writeBody("Hello
Vibe.d: " ~ req.path); });
runApplication();
}
Vibe.d no more using static this() {}
I recently noticed vibe.d now using main loop which call the vibe.d event loop. Why that change?
