If someone showed me that code (class B) and told me they didn't intend
to include class A in the runtime, my first question would be: "then why
do you reference it?"

If you want to decouple, decouple properly. Use a common class, a
resource file, a service provider interface, whatever. But don't rely on
intrinsics -- even if in this case those are fairly basic and
well-understood intrinsics. That's just begging for trouble.
