Disagreed. I'd rather keep one GetCaps that can be called by a wrapper
library (thing glib and stuff) on startup and cached so later that
*wrapper* can provide you with individual CanDoSomething wrappers.
This would reduce the bus traffic and remove the requirement of
caching the values on the application side.
