Unfinished maple necks - is that a disaster in waiting?????

[Andyxlh]

Hello all
Just thought I'd ask, I have 2 guitars with unfinished maple necks. I don't mind the grot, it looks good! but I'm a bit concerned now about the longevity of the neck stability.
One of the guitars is now 3+ years old, and still plays fine, the other is my latest bass project.
Both are stored in dry, warm areas and are not subject to damp or huge temp changes, not sure if that helps.
Ideally I'd like to keep the necks unfinished, they are really in keeping with the builds and feel lovely to play
