yes, in fact that's why SCons by default doesn't, to avoid unexpected
results from environment variables that just happen to be set - as well
as having a better chance of running reproducibly on other systems where
they aren't set....

If you do need things from os.environ, we usually suggest it's better to
bring them in selectively, and you might want to do some validation on
them if that makes sense.
