What's the point in removing ifdefed-out debugging printks?

If those debugging printks are kept under "#if 0" purposefully, then those
can be left as it is. Other parts are under "if 0" can be removed as those are
not used since 2.6.11.
How about keeping those debugging printk under some CONFIG_*_DEBUG option ?
While browsing source code, I figure out there are huge amount of dead
code under
'#if 0" and some of them are maintained since 2.6.* . I send few
similar patches for fbdev
driver and those are merged to linux-next.
But how about cleaning it in entire tree ( module wise) ? Does it make sense ?
