BPC cannot make your blacks blacker; it can only make them less black. Is that something you would want (other than in device-proofs, where you are emulating a weaker device on one with deeper blacks)? The problem with BPC is that it only works in Adobe apps, and if a profile is made to work with BPC, it won't print correctly from non-Adobe applications, except perhaps in Perceptual mode, where BPC compensation may not be used, for this very reason. So you can use our profiles from any app, with any intent. 

On the other hand, if you like the results you get using our profiles with BPC checked, thats fine too... but compare it to the version without BPC, to be sure you aren't missing anything with your particular paper, printer, and ink.
