Me too! I'll bet this will be more popular than they think. IMO, the SS is already too low with minimal clearance. I don't really get the whole down on the ground thing. In muscle car days, you jacked em up.
I am guessing you are correct. As the end user will typically be final-adjusting the machine to hit the sweet spot, we more or less assumed that anyone who would like to go stock height would just do so at that time, but pre-setting them so that the final needed adjustment will be minimal is no problem.
As for those who wish to mimic existing height (for instance, so as to maintain their current front end alignment specs, like @deaf1), we'll include detail as to how this can be done effectively and relatively easily via measurement of ride height front and rear. So long as we get precise measurements prior to removal of the current coilovers, repeating that exact ride height with the Hahn/QA1 Sphericals will be a straightforward task.
