This is intentional.  The rationale is described in the 1.7.0 release
notes:

It also follows practice established by some other popular Erlang
apps, such as ejabberd and couchdb.

But yes, this does mean that you will need to point to the rabbitmq
directory in some places where it was not previously necessary.
