Unexpected Hole in Downtube

Received a Canyon SF SL 8.0 Di2/Disc the other day. I noted that there is an unexpected hold in the down tube between the bottle cage bolts. It's crudely plugged by a plastic plug that can be removed with fingers and is attached to nothing internally. Biggest concern is that the plug is not watertight although I can obviously use some helicopter tape for this purpose.

Photos below, has anyone else seen anything similar on their Canyon, any ideas what this is about?

My Ultimate has it as well, it's used to secure the rear brake cable in the frame to stop it from rattling around. I know mine was attached becaause i swapped to eTap from Shimano and was able to feed the new hydro cable through it and then secure it.

Seen it on my new Canyon Endurace too. Had no idea what it was for though.

Why does water tight matter?
The whole frame is full of holes.
They all leak.

On Canyon disc brake bikes that is used to tighten the hydraulic hose to prevent rattling noises in the downtube.

OK, so good news then that everyone seems to have this hole. I guess they forgot to attach my hydraulic hose to it... I haven't noticed a rattling of the hose so will probably forget about it for now!

With a zip tie, like the one in it now...except you capture the brake hose in it.

Simply as this, thanks.
So somebody missed the point, I mean the cable :)
