That's an interesting point--but note that Python _also_ has WSGI and various other ways to integrate more cleanly with Apache (and various other web servers). If you just want to put up a simple web service to handle a few users (e.g., as a user interface to your application), SimpleHTTPServer is sometimes the answer. But if you want to add a web service to a major Apache deployment, you generally don't want to do that by deploying SimpleHTTPServer alongside it. It's not _impossible_ to share ports, SSL certs, configs, logs, deployment scripts, monitoring tools, etc. between the two, but it's not the way you'd want to do things. (There's also the fact that SimpleHTTPServer won't be able to handle the same load as Apache…)

I suppose it depends on your definition of "well-defined spec". As Nick said, XFCE only partly supports the spec, and he's not sure how completely GNOME does. As I pointed out, there are gaps in the spec for both implementation-defined and future-expansion behavior. That isn't the same as the case with HTTP/1.1.
Look at http://www.freedesktop.org/wiki/Software. Notice that xdg-utils does not yet have a trash command, and there is no separate trash program or library. (As far as I know, there are at least two XDG trash programs on github which have not yet been submitted to be part of the XDG software collection, which don't appear to be 100% compatible with each other. (For example, one of them requires top trash directories to have exactly mode 41777, the other just requires them to be executable for the current user and have the sticky bit on.) Does creating a third one--and putting it in the Python stdlib forever--really sound like a good idea?
(As a side note, one of the two above-mentioned trash programs is written in Node, and I don't see anyone suggesting that the functionality be moved into the Node stdlib.)
