Well, that's what I understood during the discussion of this bug and would
certainly have objected at the time if the proposal was to remove the
possibility for the CDN to set the destinationURL. Apologies if that was my
min-understanding.

The initialization exchange is one. In this case the application may just need
a one-bit indication from the CDM as to whether the message is to be sent to
the initialization server or the regular application server. The destinationURL
can be used for that (this is what I mean about the destinationURL containing
information used for routing - it may not be the actual URL, but it can be
something which selects from amongst a set of URLs known to the application).
