That is because Exim is called in unpredictable environments, and also
because it is called from user (i.e. potentially hostile) environments.
Relying on environment variables seems rather dangerous to me.

I think this would be utterly confusing. People would think they could
do this in routers and filters. But if a message is delayed, the
environment is different when the next delivery happens from a queue
runner. Or do you think the environment should be preserved with each
message?
