It would be great if it did. Just for your reference, others have tried before you.
Please check out http://tools.ietf.org/html/draft-yevstifeyev-ftp-uri-scheme-08, http://tools.ietf.org/html/draft-hoffman-ftp-uri-04, and http://tools.ietf.org/html/draft-hoffman-ftp-uri-04.

The file: scheme is simple in theory, but very complicated in practice!

Also, in your original post, you write:
> require 'open-uri'
> open('/tmp/file.txt').read {|f| puts f.read }

Of course this should NOT fail. 'open-uri' does not change open to open URIs and only URIs, it *adds* the capability to open URIs on top of the capability to open files.

Feature #8544: OpenURI should open 'file://' URIs
https://bugs.ruby-lang.org/issues/8544#change-40072

Author: silasdavis (Silas Davis)
Status: Open
Priority: Normal

Category: core
Target version: Next Major


The following code prints the contents of '/tmp/file.txt':

require 'open-uri'
open('/tmp/file.txt').read {|f| puts f.read }

which although useful should probably fail since a unix file path is not a URI, and therefore might shield data problems in a system

However the following should produce the same output and is a URI, but fails:

open('file:///tmp/file.txt').read {|f| puts f.read }

I note that the documentation for open-uri does explain that it is a wrapper for http, https, and ftp, but to deserve its name it should open such URIs as specified in this RFC: http://tools.ietf.org/html/rfc1630. This coupled with the fact that it already does open files, but not by a URI specification.
