I would...never met a guitar that didn't need a little adjustment at leazt yearly, tbough....unless you're happy with a little higher action in the summer etc...plus I tend to try different strings etc. too now and then, so basically I end up using the truss adjust on at least some of my gujtars once a month or so. Just last week I swapped sets on my V and adjusted the rod.
If I didn't do that, I'd do what you suggest now and then...maybe not yearly even but sometimes.
Never saw any rust on my guitars ever, though.
