Actually it looks like this was fixed in the meantime:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=2f170893719e6e9fc8e19cc5f0568e20a95d92b4 -- shell --export-manifest texlive-base rubber
;; What follows is a "manifest" equivalent to the command line you gave.
;; You can store it in a file that you may then pass to any 'guix' command
;; that accepts a '--manifest' (or '-m') option.

(specifications->manifest
  (list "texlive-base" "rubber"))
--8<---------------cut here---------------end--------------->8---

I’m not sure what happened, but it’s a good surprise.  :-)

Closing!
