Thinking about it, we should probably not remove the "file://" prefix.

I cannot think of any situation where [[/absolute/path/to/file]] would
match something like "<img src="/absolute/path/to/file"/>", because "/"
never matches web root directory.

IOW, to re-use the OP's example, [[/static/images/unicorn.jpg]] is never
a valid Org link, in the sense that it points to a non-existing file.
Since the OP is writing a link only valid during HTML export, he might
as well write raw HTML.

Note that that "file:///static/images/unicorn.jpg" is not useful either,
but at least it is logical.

The only situation where we might do something is during publishing,
when we know what web root directory – i.e., base directory – is. In
that case, we could replace absolute file names starting with web root
dir as root-relative URL.
