In the main all I shave is my face and head.
But maybe 3 or 4 times a year I will have an all over groom.... chest, underarms, nipples, bollocks....
I don't see a problem with it. Wouldn't do it weekly or anything though.
If I'm going on a beach holiday I'll shave my chest approx 6 weeks before I go to give it time to grow back to a nice length. Completely shaven looks daft, but too long and hairy looks horrible, so its all about getting it just right.
