Why is UnityEngine.xml included in builds?

Why is UnityEngine.xml included in builds, especially mobile?
That’s 1.6MB (like 170kb compressed) of Intellisense documentation being put in final builds.
I can’t think of why that would be needed for device builds.

what platform ? there’s currently an open bug i reported that this file is included in the iOS builds…

I believe I was testing Android at the time, but I think it exists in both, but don’t understand why it would.

Did you create a development or an actual build?

It shouldn’t. that’s a bug.

I am creating a normal (non-development) build.
