That's a understatement Artemio. Day one after you released the means to reboot cps2 all in one as a example, someone used it for sinister purposes.
You can also argue this lowers the value of original/purist hardware.
Of course people are going to use information for their own means, but implying information should not be released because people could abuse it is paternalistic as well.
Regarding peace of mind and battery use; I keep my collection stock, and have a database worth dates on battery change. I also measured ESR of the batteries I used when new, and after use. That gives me a life expectancy.
On top of that, I have a raspberry pi with thermometers and higrometers controlling a dehumidifier and generating statistics on order to have controlled conditions. I did that because my arcade room if close enough to the garden and kitchen.
Battery leakage hasn't been an issue this way. I've changed them every 5-7 years, and most of them could easily give 10 years under these conditions based on the limited statistics and measurements I have.
The point is, you are not limited to that now. I'm not suggesting you kill your boards now, store them and only place a battery after prolonged storage and desuicide them. But that is now an option.
It also will hopefully help find undocumented variants. Either because people have them stored dead, or because less boards will be phoenixed now that it is not the only option, erasing their original data. I've found at least 10 undocumented ones in the past 8 years this way.
Speculation is a bad thing indeed. But people can view it in very different ways. Some will feel boots will flood the market. Some others know they have dozens of originals stored and dead, that can now be brought back without using a phoenix set. Those will now be able to enter the market. Some will not see a value difference between a dead or alive board of it is stock. Some won't see a difference with a phoenixed original board, since it can be restored.
