I noticed the same problem (most important with multiple registrars I
didn't like paritioning logic) and my solution was to send my own OPTIONS. 

In your favorite scripting language, select all location entries and
construct an OPTIONS and send that directly to the correct proxy with a
preloaded Route (based on Path headers inserted on the proxy). In the
response I defined a valid reply as a response code other than 408 and
below 500.
