I am seeing this idea as a drunk trying to fly a ship. Like a drunk driver trying to drive a car today. Only if it had this or that so I can live. This idea is not needed, a little common sense can go a long way. If all else fails you can use system repair unit to repair the power unit to 1%.
Common sense is a skill. Laziness or being drunk is not a skill.
You seem to be forgetting something, even the most skilled & careful pilots will make mistakes occasionally, human error is always a possibility. It's not about laziness!
And repairing the PP to 1% isn't enough, at what level is power generation at that health level? I bet it's a long way down from 100%, so we wouldn't be able to use some modules.
Btw, incase you're replying to just the op & you haven't read the rest of the thread, I'm not asking for a 2nd PP but a back up battery, just enough power to run the AMFU so it can repair a damaged PP to 100%.
Also, Drakkath's excellent idea is to enable the power stored in the Distributor to be fed back into systems, again to allow the AMFU to repair the PP.
It makes sense to be able to fully repair the PP, especially when you're 1000s of LYs away from any stations where limping home on a 1% PP may not really be an option (depending on how much spare power capacity you had in the 1st place).
Also, the PP is now (I think! lol) the only module that can't be repaired (bar the 1% reboot option).
