That configuration is mostly a safe guard against very
slow preview drawing times. Even with OpenSCAD not using
much of the power of new graphics cards, they are more
capable by the minute, so increasing that config for a
normal desktop machine is no problem.

This tries to explain (not very well, I suppose) the reason
why that "normalized tree" can explode:
The best option that help against that is what nophead
said - use render() to force geometry calculation at
specific points (like complete modules of an assembly).
