There are good reasons to do that:
Wanting to shoot it and not risk the old wood, i.e. there could be splits that could be exacerbated by shooting, etc.
The dings and nicks could be bad enough that it is right on the edge of acceptable or comfortable to the owner.
Wanting to repair the old wood and have plenty of time to consider the best route.
Wanting to experience something of what a new recruit in '44 felt when he drew a shiny new weapon.
I've done that very thing with mine while I consider what to do with a badly split fore-end.
