I know I sound like a broken record :) but is there any way to represent these
types (device IDs, UUIDs) with more specific types, whose constructors assert
sanity?

I'm currently working on a follow up patch to use BluetoothUUID instead of just
strings: http://crbug.com/606446

Currently there is nothing of the sorts for device id. We could introduce one
which would help http://crbug.com/577962 but the only validation we can do is
regarding the string's format: length and last two characters. jyasskin and I
agree that it is something we should do but that the payoff isn't that high.
