I agree with developers concern but I also see the concern you have about  
fingerprinting, so question: would it be a solution to let the application  
declare (maybe via markup) which actions it "intends" to use, so that the  
user-agent can warn the user that he has no providers registered for such  
actions (and maybe offer a list of providers he may want to go and check)?

This could be aligned with what I suggested above, so you can declare  
which actions you rely on and optionally point to some you know are
