I have no idea here you get this idea. The whole idea of /etc is to hold
files that configure a system that might be managed and modified by the
admin. You had better know what you are doing before editing these but I
have had many files in various systems that I customized and that was the
whole idea of the /etc directory at least back in BSD4.2 (NOT FreeBSD!).
The reason we have /etc/defaults is to have a safe, reasonable set of
defaults that should NOT be modified. If FreeBSD update or any other
mechanism simply over-wrote the files that had been modified in /etc, I
could no longer use them as I have NEVER had a system where at least a few
files in /etc were modified. Yes, that includes scripts.

/etc/rc.s are a bit less likely to be edited, but I used to have quite a
number that I modified on my personal systems to modify shutdown actions.
Still, I agree that this is a bit unusual and updating by default might be
reasonable.
