Silly me: we cannot have $HOME/.guix-profile/share/icons and
$HOME/.icons in ‘XCURSOR_PATH’ if we do it via
‘session-environment-service-type’.

So I guess we have to go with /etc/profile as in your patch.
Can you push the patch (with a comment linking to this issue)?

Right.  In the patch, I think you can add the extra ‘search-paths’ entry,
comment it out, and add a TODO comment.

Definitely.  :-)
