Unlock app implementation query

[Engarde]

Apologies if this has been covered to death already but since I'm one of those with stock android where smart lock works for minutes, I'm curious about the basic differences between the app versus smart lock.

So if I register a ring/facet/tag with the nfc unlock app I consume that facet's space to the tune of MIME:nfcringunlock/key, where in smartlock mode my tags are otherwise left free.

I'm curious why the nfc unlock version went with using a mime tag to trigger the unlock rather than some aspect of the ndef etc for the ring being registered.
