I like the idea of using SDNodeFlags for keeping information represented in FP bundles. The changes necessary for implementing this feature could be moved to a separate PR, so that it could be committed prior to implementation of the FP bundles. It would be difficult to test these changes while the FP bundles are not available, but probably unit tests could solve this problem.
