That's a fair point. The lower level stuff and NDEF format is well standardized. The higher level operations are not nearly as well standardised right now, even more so when you're dealing with large files, which will require a handoff to Bluetooth or WiFi Direct. In NFC's defense, it's only recently (4.2, Jelly Bean) that Android even supported transferring large files via Bluetooth handoff, so hopefully that stuff will improve with time.
