> We should get a choice on that.
this is it exactly. They should not remove manifest v2, they should make it more explicit that an addon is v2 or v3, and let the end user choose (with the default being v3, and deny v2 addons).
When an untrustworthy addon asks to be a v2 addon, the user can be made more suspicious, but allow addons like ublock to remain working at full power.
Of course, the whole reason google did it is to remove effective adblocking.
