Dear,
An update to say that the situation is maybe worse.

--8<---cut here---start->8---
guix time-machine --commit=f678cc9 -- build emacs
guix time-machine --commit=f678cc9 -- build emacs \

files are:
--8<---cut here---start->8---
$ diff -r --no-dereference /tmp/emacs.{1,2}
Binary files /tmp/emacs.1/bin/.emacs-26.3-real and
/tmp/emacs.2/bin/.emacs-26.3-real differ
