Default 2012+ Impreza Hard to start? Fails to start the first time? Hard cranking? (SOLVED)

Edit: See/Google discussion over TSB 11-156-15, Reprogramming File Availability for Extended Engine Cranking (Delayed Starting).

Other TSB #s:
11-153-15R Technical Service Bulletin Reprogramming File Availability for Extended Engine Cranking May 27, 2015 [View PDF]

11-156-15 Technical Service Bulletin Reprogramming File Availability for Extended Engine Cranking (Delayed Starting) May 27, 2015 [View PDF]

This seems like an appropriate place for most of us to declare it solved. The TSB, and the description on the TSB, VERY closely, if not exactly, describes the problem, and purports to fix it.

Original Post:
This issue was brought up several times in the 'News and Rumors' section under the 2012 Impreza thread. With that thread hitting its limit...

Several people have reported that they occasionally experience a car that is hard to start, or cranks hard, or simply fails to start the first time.

I have had this happen to me 4 times now, I took delivery on it December 31st. 2 times for me were at home, car cold, 2 were at work on the weekends after the car had sat for ~2-3 hours after being warm. Only one time was in "winter" cold of <20 degrees F.

The only other threads relating to hard starting are from 2002 or older...hopefully this is the correct place to post this.

I'll include all details that have electrical/mechanical bearing on the car.
