I don't know exactly how Commons is making use of Addressfield Tokens, so this is obviously in need of your consideration. However, with the release of Addressfield 1.0-beta5, the module now includes a core set of tokens for addressfield data values. The Addressfield Tokens module has a small bit of extra functionality in it, but if that functionality isn't essential to Commons, I'd recommend removing the dependency and reconfiguring your events functionality to use the core tokens instead.

See #1188778-43: Add token support for the various elements of an address field for my summary of the implementation.
