It's nice to see Google repurposing Microsoft's project name of "Canary". I'm reminded of this classic Reg article:

The codename for the Microsoft phone was "Stinger" until everyone called it "Stinker". Choice quote:
(Microsoft hates the "Stinker" moniker so much, that it's
rebranded Stinker as "Canary" - perhaps unaware of the bird's
history as a sacrificial and disposable early warning system for
miners. When the Canary dies - you clear out fast).
