The issue is that I think it's then _misleading_ to mark that kind of 
commit specially, when I actually believe that it's in the minority.

If people think that they are safer for only applying (or upgrading to) 
certain patches that are marked as being security-specific, they are 
missing all the ones that weren't marked as such. Making them even 
_believe_ that the magic security marking is meaningful is simply a lie. 
It's not going to be.

So why would I add some marking that I most emphatically do not believe in 
myself, and think is just mostly security theater?

I generally do not remove peoples changelog entries, although I _will_ 
do even that if I think it's just too much of an actual exploit 
description (of course - the patch itself can make the exploit fairly 
clear). So you'll find CVE entries etc in the logs if you look.

But I do hope that anybody who looks for them is _aware_ that it's just a 
small minority of possible problems.

Don't get me wrong - I'm not saying that security bugs are _common_, but 
especially some local DoS thing for a specific driver or filesystem or 
whatever can be a big security problem for _somebody_.
