My only worry is that next time we have to do something non-standard,
we'll have to annotate it as well. bpf_jit case-in-point.
OTOH, I guess the generic, tool-agnostic annotation could be a step
in the (more-)right direction as we're saying "we're doing something
special here, and we're stating that fact with this here annotation."
