This is certainly one way to go, though it can add additional complexity for both DM and player, particularly in the case of multiple characters.
I think the most important point is not to make the campaign excessively lethal. It's fine to kill characters. As has been mentioned, character deaths can be important moments in a campaign. However, once a campaign approaches a certain level of lethality (that measure of a "meatgrinder" being admittedly subjective) players will tend to lose a degree of attachment to their characters (IMO), and the campaign will be poorer for it.
Personally, I think making "throw away" fights either nonexistent or unlikely to kill the party is a good approach in that regard.
