What I'm wondering, too, is, why a seperate server-process (which seems nothing more than a WebServer) is neccessary at all.
Wouldn't it be enogh to write some sort of WebApp (in PHP or whatever language) that deals with the calibre content, offers an OPDS Feed in a completely read-only way and let Apache or NGinx serve it?
Then one could use all the features of a "real" WebServer with all its modules (Basic Auth in many different ways is the first that comes to my mind), so concentrate on the plain "Business Logic" and don't have to deal with how to implement all the HTTP(S) - Protocol / Auth / Security stuff...
But I think, there will be some good reasons, why calibre-server exists..

Minimal PHP webapps that look at your calibre library and serve files, already exist. calibre-server does much more than that, however, and I don't really understand why you care which language it uses to implement complex read/write operations that query a database and can modify files as needed in-transit (cf. plugboards) etc.
And it also needs to implement auth, protocol, etc. because not everyone wants to set up an apache instance in order to use calibre's Content Server.

This is complete and utter nonsense. There are many server applications powering important things on the internet, which are self-implemented in, for example,
python 
rather than being written in PHP.
