It's not "totally redundant" _AT ALL_.

"2.6.30+-2-amd64" tells us that not only do we have the usual per distro
patches on top of vanilla .30 (which patches can be found in the deb or
src.rpm), but we _ALSO_ have extra _vanilla kernel_ commits since

So it is very much meaningful. If i hunt a weird bug visible in a distro
but not visible in my reproduction, i will be alerted to the fact that
the distro isnt using a precise tag as a base but something inbetween.

That is useful information. Why do you keep insisting that it's "totally
redundant"? It is clearly not. It's a property of the upstream kernel
version - any per distro pile of patches on top of that is a different
space. _Both_ pieces of information are important - that's why Debian
put that -5 there.

Besides, distros building on kernels inbetween -rc's is very rare. If it
happens it's sufficiently unusual to alert users to that fact via the
'+' sign. The '+' sign will go away if a distro uses a precise upstream
