It's not really a wired/wireless thing at all.
Polling is an option (theoretically) here too. "Not polling" is a design choice.

The head unit having a "pairing mode" is a requirement. The sensor having such a mode is not a requirement (whether or not there's a benefit).

Being required to put the sensor into a pairing mode would keep the head unit from pairing with sensors on nearby bikes (not that unusual a situation).
Two sided pairing is required to make a single channel for two-way communication (common in Bluetooth).

You reset the Bontrager by putting in the battery backwards for 2 seconds.
The reset button on the Garmin GSC-10 appears only to be used when setting up the sensor with the magnets (it isn't used when pairing).
The way the Bontrager works, it doesn't need a reset button for set-up.
