Don't worry about this at all. It is common. The seals in these types of water pumps are mechanical but not perfect. They can and will leak slightly, the weep hole is there to allow the weepage to drain and to monitor the condition of the oil and coolant seals.
BMW is having an issue with a bunch of it GS's with this very same issue, and it's mainly because the water pump and the weep hole are in plain view on the right side of the bike, so the weeping from the pump are obvious and unsightly. I have had three water pumps on my F800GS, BMW replaced it twice under warranty.
What they ended up doing for later model years was to put a drain hose from the pump to underneath the bike so the weeping is not obvious.
Some DO leak excessively; my first repair did not leak coolant, but the oil seal was bad and it was constantly leaving streams of oil along the cylinder and top of the clutch cover. That was excessive, so they repaired it once again, and it seems to be just fine after several thousand miles.
My FZ8 also shows some slight greenish weeping from the weep hole, but very minor.
Kawasaki is taking the same position as BMW for most of these claims, monitor it but ride the bike. In time, the mechanical seal will usually wear in and stop leaking, or at least will reduce leaking to an acceptable level.
Now I will go check mine to see how it's doing, coming up on 8000 miles.
Forgot to mention you cannot get coolant in your oil or vice versa, the two fluids are separated by an air gap and the weep hole is common to this gap.
If the oil leak is excessive then you have good claim there, but wipe it off and ride it, monitor it, and if it continues then pressure KHI to fix it. It's a quick, easy fix. Coolant and oil leaking from a motorcycle are not a good thing.
