binary patches?

[Gary Kline]

	Regarding most (or many) of the port changes--say, upgrading
	foo-2.1.9_5 to foo-2.1.9_6, if  the upgrade could be done by
	downloading a binary diff file, could the resulting
	/usr/local/bin/foo-2.1.9_6 be achieved by downloading a 
	relatively small binary patch?  Seems to me that smaller scale
	upgrades could be done this way in preference to re-compiling
	ports or downloading entire pacakes.  --Same would go for any
	dependencies.

	Why is this a bad idea!
