Expression property in Annotations

[Coneys]

Hello.
I am trying to change line-width from simple float, to interpolated expression, something like:
PropertyFactory.lineWidth( Expression.interpolate( Expression.exponential(2f), Expression.zoom(), Expression.stop(10, 1f), Expression.stop(18, 3f) ) )
Unfortunately, I cannot find way how to do it with LineManager. It accepts only float as line-width, and I cannot write into jsonObject to use data driven styling without using reflection. How should I do it?

Or maybe there is new fancy way that will disable ugly polyline scaling on zooming out, and I shouldn't bother with line-width anyway?

Any updates on this?
