Won't happen in this case, this doesn't apply to files in /etc
at all; it only applies to the default /root/.shrc and /root/.profile
that get installed on fresh systems.

It doesn't.  For sh(1) to read ~/.shrc (/root/.shrc in this case)
you need to have ENV set; the default /root/.profile only sets
it when sh(1) is your login shell.  Which means, this doesn't
change the behaviour when you casually run "sh" or "/bin/sh"
as root; sh needs to be set up as login shell for this to take
effect.
