A friend of mine has one that he mostly uses for music. I've noticed that every time I visit his commands have had to get slightly longer.
2016 - "Hey Google, play Gorillaz"
2018 - "Hey Google, play music by Gorillaz"
2020 - "Hey Google, play music by Gorillaz on Google Play Music"
2023 - "Hey Google, play album Demon Days by Gorillaz on Google Play Music"
One day the previous command will suddenly stop working with a "I don't understand" error, so he has to figure out the new incantation to get it to do anything remotely close to what he wants.
