I use timers for making tea, cooking and knowing when my car has finished heating up.

Unfortunately iOS only supports one timer at a time so I can't make tea while my car is plugged in.

Weirdly, HomePods do support multiple (optionally named) timers. Since they're also based on the general iOS family, there's a bit of hope for the feature eventually making its way to the phones. I'd assume it's held up on them having to redo the UI, if anything.
