That's not a rule we have.  I'm in two minds about whether we should
write it in.  If we want to have this happen, we should definitely say
that it's possible though.

I was imagining a case where you have VAPID tokens issued on a more
granular level than you have receipts being routed.  Imagine you have
one receipt subscription per region, but a single centralized
controller of the VAPID key so that all the different regions can be
counted by the PS as a single entity.  In that case, inferring from
VAPID might cause the application server some issues.
