As usual, mileage varies. I didn't test the case of a proxypass at
server level with a balancer there as well... here is my config:

BalancerInherit Off
<Proxy balancer://mycluster>
  BalancerMember route=1
ProxyPass /proxy/ balancer://mycluster/

ProxyPass /proxy2/ balancer://mycluster/

Attempts to hit /proxy/ on that vhost work every time (with
BalancerInherit Off). Attempts to hit /proxy2/ return a 503 and
"AH01171: balancer://mycluster: No workers in balancer". I'd say that
the former is definitely unexpected but the latter is fairly reasonable.

There was a ProxyPassInherit as part of the original patch... maybe that
needs to be revisited?
