Emacs is not reproducible

[Bone Baboon]

I am using the Guix operating system.  It provides tools to verify if a 
software package is reproducible. 
<https://guix.gnu.org/en/manual/en/html_node/On-Trusting-Binaries.html#On-Trusting-Binaries>
 

For details on how Emacs 27.2 is not reproducible see 
<https://issues.guix.gnu.org/issue/35085#7>.  Previous versions of Emacs are 
also not reproducible as reported in that thread.

For information on why reproducible software is important see 
<https://reproducible-builds.org/>.

For information on how to make software reproducible see 
<https://reproducible-builds.org/docs/>.

Is there currently any work underway to make Emacs reproducible?
