Amen to this - we have an old maple that has been cabled to help carry the 
weight of its branches, using through bolts and wire rope.  It is very 
happy, and has been for a decade.  On the other hand, if you damage enough 
of the cambium, the circulation layer right under the bark, it will kill 
the tree or the branch above the "girdle."  Last year, I scraped off a 
patch of the bark of a young maple with my mower deck, and the branches on 
that side of the tree above the damage simply stopped growing.
