Quick follow up on this.
Personally, I don't think we should discourage the creation of new
layers that use specific formats, protocols, and strategies.
The vector behavior design was supposed to encourage reuse of common
code rather than discourage new specific layer types.
Not sure how others feel, but if someone wanted to create a specific SOS
layer, I'd be in favor of including it.
Disclaimer: I have no idea if someone could create an SOS layer that
would be useful in multiple applications.
