There's a pretty widespread convention that %b is used to print in binary: printf("%b", 10) -> 1010. Regrettably it isn't part of standard C, but it's often supported anyway. Perl's printf does this as well. Perl uses %B also.
If we later want to add binary printing to kernel print(), we'd presumably use %pb, to match this precedent.
So perhaps it would be better to avoid consuming `b' for bitmaps?
