"Delete change" Gerrit feature was available for a limited time, and I've successfully deleted some 3 year old changes (don't worry, their work has been merged at newer changes - I've double checked it well before proceeding - so nothing lost).
However, someone used the same feature to remove the valuable "Switch away from ROMCC_BOOTBLOCK" changes by HAOUAS Elyes - to which I've spent a huge amount of time contributing the minor fixes and reviewing. This "switch away from ROMCC_BOOTBLOCK" work has been declared as a mandatory condition of preserving a range of AMD boards, so it's really sad to see it gone. Gogol burning Dead Souls volume 2 comes to mind...
Please, restore the changes deleted since Jan 5 2020, and make sure this anti-feature "delete change" can't be used such easily in the future.
Best regards, Mike Banon
