These symbols are being explicitly exported (check the header files). See below.

The symbols cannot then be hidden (otherwise the server will not find
them). So they will be a noise factor _forever_. I'm wondering if this
is a correct design decision (having a single library for both a
public and a private API), but it's not my call to make. I think we
should trust upstream and just shove a libjack0.shlibs with >=0.116,
and be done with it.
