Why can't home smoke alarm systems be nearly as good as commercial-grade?

I was frustrated you cannot have normal fire drill functionality with any home solution, including many of the "smart" home solutions. What if you wanted to put your smoke alarms into activation? You would either have to climb a step ladder and press the button on one of the detectors or use fake smoke. Plus, there is no easy way to silence them (except smart home solutions).

This inspired me to purchase a commercial grade system. Not only can I have fire drills by easier activation (via a pull station or panel button), but my smoke detectors can detect heat too other than smoke and have built-in sounders just like home smoke alarms.

I hate I had to pay several hundreds of dollars for this, but I wanted more control over my alarm system.
