I just got a patch in to JOSM to automatically delete certain TIGER and CanVec tags from modified objects during upload. Thought I might as well try to get P2 to do the same. These tags have been deemed unnecessary by the relevant communities and are just cluttering things up. This behavior is already in place for the created_by tag.

Here is the JOSM ticket:
https://josm.openstreetmap.de/ticket/7915

The tags to remove: [[BR]]
tiger:upload_uuid [[BR]]
tiger:tlid [[BR]]
tiger:source [[BR]]
tiger:separated [[BR]]
geobase:datasetName [[BR]]
geobase:uuid [[BR]]
sub_sea:type [[BR]]

The JOSM devs also added odbl and odbl:note to the auto delete list now that the license change is over.

Looks like the current logic to drop the created_by tag is in [http://git.openstreetmap.org/potlatch2.git/blob?f=net/systemeD/halcyon/connection/XMLConnection.as#l456 XMLConnection.as] around line 456.
