The part about failover is orthogonal to the decision about misc-web.  Our 
standard model for a raw internal service will be to LVS it across redundant 
backends as discussed in the other ticket 
(https://phabricator.wikimedia.org/T107601), but this ticket/commit are about 
how present the frontend of it to the world via standard termination on the 
public LVS/cache endpoints (which will then backend into the 
https://phabricator.wikimedia.org/T107601 internal LVS'd endpoint).

I don't think we've ever really elucidated exactly what differentiates misc-web 
from text-lb for termination.  The easy cases are obvious, but there's a grey 
area too, and this is a somewhat-grey case...
