Inheriting environment variable is under the user's controll. Finding a
readable file by the user is less (requires to start x11 sessions in a
specific order). By more controll I mean the user could stop Shepherd on
a DISPLAY :0 and start it on DISPLAY :1 without stopping x11 sessions.

In any case, current patch with or without specification of files order
(or ‘herd start x11-display :42’) will change current behaviour. So, I
think a small entry in ‘news.scm’ could save somebody a day.
