It's used mostly in logs and we already wrap values there. So, right now log message with snapshot id in it looks like this:
````
[2013-10-24 14:52:06,383][TRACE][index.snapshots.blobstore] [Nital, Adri] [[index_1][0]] [my_backup:snapshot_2] writing shard snapshot file
````
If we follow your suggestion, it will look like this:
````
[2013-10-24 14:52:06,383][TRACE][index.snapshots.blobstore] [Nital, Adri] [[index_1][0]] [SnapshotId: [ my_backup: snapshot_2 ] writing shard snapshot file
````
I think I prefer the first one, but it's not very strong preference.
