Yes.  I put it there on purpose.  It's a "should" requirement for shared 
libraries.  See policy 8.6.3.  C++ symbols are, however, particularly hard to 
manage well.  The Debian Qt/KDE team has come up with some specific tools to 
make this work better, which I used to create and update 
debian/libopendbx1.symbols.  You can find information about it here:

I believe we can make the symbols optional, but we're operating at the edge of 
my knowledge on the topic.
