In the 744, the ILS heading is automatically set in the MCP when the LOC is captured. No pilots that I fly with make any changes to that.
I don't think there is any need to reset the MCP when you have a Track-up display and a working Flight Director -- it would be just one more distraction at a critical phase of flight. Besides, wind changes near the ground are quite often significant, and constantly resetting the MCP on short final would be ridiculous.
There may be other good ways to do it on non-FMS airplanes or those with "Heading-up" displays...
