My point is the end user chooses what this pager is. For instance,
in the ps output, as a child of journalctl:

vlefevre  112315  112314  0 16:03 pts/15   00:00:00 /bin/sh /home/vlefevre/bin/pager

The fact that the user doesn't run it himself doesn't matter.
So there is no such thing of "fixed and tested environment":
the user has the full control of what is run.
