I badly worded. Sorry.

As Ricardo pointed [1], the Emacs doc [2] says:

--8<---------------cut here---------------start------------->8---
 Emacs sets the environment variable INSIDE_EMACS in the subshell to
 ‘version,comint’, where version is the Emacs version (e.g.,
 ‘24.1’). Programs can check this variable to determine whether they are
 running inside an Emacs subshell.
--8<---------------cut here---------------end--------------->8---

So EShell should manage INSIDE_EMACS since it could be considered as
an Interactive Shell or subshell.
It is how I understand it. Maybe, I misread.


Well, concretely, if you use EShell and you want a readable "guix
describe", you have to put in your '.emacs' config file something like
'(setenv "INSIDE_EMACS" "1")'. Or you should patch EShell and report
it upstream.
