This is what I would expect, but this is not the case. E.g. when 
installing "dino", a GTK application providing .desktop file, 
XDG_DATA_DIRS is not defined in $GUIX_ENVIRONMENT/etc/profile (same for 
a profile)

$ guix environment --ad-hoc dino

# Proof dino "somehow" has a search-path definition
$ grep -E 'XDG|GTK' $(which dino)
export XDG_DATA_DIRS=…
export GTK_PATH=…

# Proof environment has a "share" directory and there are .desktop files
$ ls -F $GUIX_ENVIRONMENT
bin@  etc/  include@  lib/  manifest  share/
$ ls -F $GUIX_ENVIRONMENT/share/applications/
im.dino.Dino.desktop@  mimeinfo.cache@

# Proof XDG_DATA_DIR is not set for the environment
$ grep -E 'XDG|GTK' $GUIX_ENVIRONMENT/etc/profile
$  # no results

As shown above, this does not always hold even for GTK applications.

Have you installed gtk+ in your profile? This package is the one 
defining search-path GUIX_GTK3_PATH.

(When installing gtk+ in my environment/profile, I also get 
GUIX_GTK3_PATH defined. gtk+ propagates atk, which propagates glib, 
which defines search-path XDG_DATA_DIR - which is why XDG_DATA_DIR is 
also defined in the etc/profile.)
