Is there a design philosophy behind the decision not to implement permanent viewport construction guides?

Hi Jon yes in the future I would like to figure out some way to have "sticking" construction lines in some built in way.

Mainly it's intended that if you need persistent construction geometry you would just draw whatever regular lines, circles, planes, etc... and just name them or assign them a particular style to keep them separated somehow from your regular objects.
