Yep, epoxy can take a lump of wood off with it when you prise it apart. Having watched an experienced Luthier struggle to take off many a Martin and Gibson neck with steam injected into the fingerboard around the neck joint, you wouldn't want to make it even more difficult with epoxy. Like I said, if you are concerned about a well glued joint, Titebond is actually stronger than the wood it glues, once set.
