RFC: etcupdate tool in base?

I've had several folks ask me recently about importing etcupdate 
(http://www.FreeBSD.org/~jhb/etcupdate) into the base system as an alternate 
tool for updating /etc during upgrades.  Do folks have any strong objections 
to doing so?  More details about how it works and an HTML version of the 
manpage can be found at the URL above.
