4.12 Released!

4.12 Reflection Plane - Options for speed?

I haven’t installed 4.12 yet but I have a question regarding the new Reflection Plane .

“These work by rendering the scene again from the direction of the reflection, so there’s a significant cost to using this .”

Is it then possible to [x]disable features from the 2nd reflection (e.g. foliage, anything heavy that doesn’t need to be in the reflection) to make the plane reflection render less costly and thus faster?

If not, could this be a request?
