It's true that that they are bugs, but on such widespread errors that are transparently fixed by the kernel, do we really need to be reminded every time such an event occurs?
$ grep unaligned /proc/cpuinfo kernel unaligned acc : 0 (pc=0,va=0) user unaligned acc : 4400 (pc=30281c8c434,va=30281db8f62)
This machine has been up just a few hours, and already a has fixed a lot of these errors. I really dont need the signal:noise ratio of my logs diluted by this, unless im searching for bugs, which is why a sysctl makes sense, imo.

True, and thats _really_ useful for turning the messages _on_ for the application your working with/debugging/etc, system-wide messages just dont make sense to me.
Also, it is optional, so only users who foresee wanting to disable the messages will do so.
