In fact I'd go further and suggest explicitly wiping out %ENV, and only setting the items that you need. That will eliminate time bombs from various modules that might use environment variables in unexpected ways. (Particularly cases where after an upgrade, the module adds an environment variable that it didn't use before.)

Note that if you really did want something like PATH to be settable, you can untaint it (presumably with a sanity check) and set the value to the untainted version.
