Which app were you using with your Nexus 10 to test @Gordon? I used both NFC Tools and NFC TagInfo by NXP, the latter of which created far more NFC events.
With both apps and @AntiCat's FW, I can see Select CL1 commands reaching the JS event system (would have expected these to be handled and not propagated).
