Reading a tad more into it. "Extras" by default would not require a Mobile Operator to make a decision to include it on their distributed devices. They would have to make a conscience effort to exclude it.
If these devices are provided by the Mobile Operators in the "closed" mode then a customer might have to go through the additional cumbersome, and possibly shady steps of "unlocking" the device before they would have access to community developed applications.

What little I once knew about such things was before Apple changed the nature of relationships between Mobile Operators and Manufactures. All of this is supposition on my part. Depending on Nokia's agreements with them, Mobile Operators may even be compelled to provide all Nokia Default applications and repositories.

If these suppositions are correct then that would be a horse of a different color. With "Extras" enabled by default, community developed applications would have a pipeline to all users and the answer to the question now becomes a "no brainer".

My apologies to the developers and others who saw this earlier.
