We use nodemasks in our scenegraph to do things like figure out what can be picked, what can be shadowed, etc. When we load data most of the time the nodes come in with masks of 0xffffffff. Occasionally we get an .ive or .osg file that has some other value set in the nodemask. We are going to reset these values under the admonition "it's our scenegraph. we control those bits". If we leave them alone we have to figure out another way to do picking, shadows, etc.

So my question... is this bad practice?
