Makes sense; even if you aren't at a raised securelevel, I'm not sure
you'd want restore to modify "unchangeable" files.  But then again,
one would need some way of handling your situation...

In any case, make sure you do this without securelevel.

It shouldn't (and doesn't for me).  Maybe the inode was changed for
some reason?
