What about NSEC/NSEC3 chains?

There are cases where having your own version is more than reasonable. Apart from the minimum disclosure case (that would be covered by an "off" switch) it may be that we have our own modifications to the stock releases. Sure, if we're hacking the source we can of course hack the part that specifies the version string...but we all forget about such maintenance while we're chasing the real problem, so being able to just tweak the config to indicate that this is not stock knot-1.3.0 but rather my own derivative version would be helpful.
