Thanks!

Note that there is the "--manifest" option to "guix environment".
This brings up another "pro" for manifest: Right now it's possible to
create environments out of manifests while it's not possible to create
environments out of profiles without Chris' hack.
A question that I believe has been brought up before: is it possible to
specify multiple manifests from the command line, such as to provide the
union of the manifests?
Even better: what high-level functions to manipulate manifests, such as
"manifest-union", "manifest-difference"?
Then from command line we could something like the following:
--8<---------------cut here---------------start------------->8---
guix environment --expression '(manifest-difference "manifest1.scm" \
(manifest-union "anti-manifest1.scm" "anti-manifest2.scm"))'
--8<---------------cut here---------------end--------------->8---
Thoughts?

Shouldn't it be '"$1"/etc/profile'? And no "exec ..."?

Can you explain why you need to repeat $@ here?
Cool hack, thanks for sharing!
