However it is possible to get a full set of Device Keys from nowadays version. One of these keys is key 2 (or 3) of master tree (22 level), other of these keys is key 2 (or 3) of one of the two 21 level subtrees and so on. This is a big chunk of keyspace, and this chunk is no longer available for future revocations.
Sure, keyspace is huge, but it is limited anyway.
