Actually, I looked at my implementation and it's not actually receiving anything except the command line parameters. I am reading the body from the spool (ick). I am actively trying to tweak the router to optionally pipe the entire message (not sure which RFC... x822) to the external command. I know it's heavy-handed but I haven't come up with a better solution.
The mail configuration I have basically does the following:
(1) Filter as much incoming traffic as possible using DNSBL and static blacklists,
(2) Pass the message to a web service to be inspected/routed (whitelist/graylist/blacklist); These rules are maintained by an operations team and change frequently.
(3) Optionally forward the message to end recipient.
I thought about doing all of this in a pipe transport but I have fewer options at that point should something go wrong (although that's just my gut feeling).

Currently, I am only getting the message body piped to my external program and I have to pass the SMTP header via a command line switch (gross). I am wondering if:

The book (ISBN 0-9544529-0-9) says "No input is provided for the command" - which seemingly does not match what you find in practice.
To be clear: you're getting the 5822 body but not the 5822 headers
(and you'd like the latter)? You're not referring to 5821
envelope information?

I don't see one.

Certainly; open a bug at
https://bugs.exim.org/ (and label it as "wishlist").
No promises on when or if, I'm afraid.
