Why Doesn’t Apple Include a Native Smart Alarm Feature on Apple Watch?

I’ve been using my Apple Watch for sleep tracking, and I’m really impressed by how well it works. But one thing keeps bothering me: why doesn’t Apple integrate a Smart Alarm feature directly into the built-in alarm system?

The watch already tracks sleep stages and collects detailed data. Adding a smart alarm that wakes you up during a light sleep phase wouldn’t be a big leap—it feels like such an obvious feature to include! I know there are third-party apps like AutoSleep or Pillow that offer this functionality, but I don’t want to rely on external apps for something that could easily be native.

This would make the Apple Watch even more user-friendly and complete as a sleep companion. Does anyone else feel the same way? Or has Apple ever explained why this isn’t included?
