Yes please Apple! If you want HomeKit to succeed and become the leader in the smart home space you desperately need to implement some easy way to read NFC tags from the watch. Battery drain could be mitigated by only enabling NFC reading for a couple seconds after you long press crown when Siri is up, if no tag is detected it could turn off. Most people will not be using Siri so often throughout the day where it would negatively impact battery life. Although with the geniuses you have working at apple I’m sure you can come up with an even more user friendly implementation that could be done completely hands/voice free without any button pushes or hey Siri cues, while also keeping battery life to all day long.
