We haven't allowed this, so far, because it would mean that merely
opening a file in DrScheme would be enough to have code downloaded and
installed on your machine.

Running a program that uses a Planet library also downloads and
installs, but you at least have the option of looking at a file and
deciding whether you trust the libraries before you execute it.

Probably the solution is to allow Planet paths in combination with a
dialog that notifies the user that code is being downloaded, and that
proceeds only if allowed.
