This means you need to implement stat(). When the URL doesn't end with a slash,
kde doesn't know what type of file it is - so it calls stat().
Make sure to also call mimeType() as the first thing in get().
In fact get() should be called most of the time, even from e.g. minicli, now ...
but it _needs_ the mimetype to be emitted.

That's only "to conform to the RFC about URLs". I don't think it
brings any problem to do otherwise.

Nope.

Doesn't sound necessary to me.
