more than automated static analysis. You have to look at each of the
potentially-private interfaces and decide if it should be public in
spite of there being no use for it that you can find.
Conversely, just because you can find one application and/or plugin use
of some symbol doesn't mean it should be exported -- that application's
use of that symbol might be a bug, along with the symbol's being
exported. If you can find no other such apps, and if you can fix that
app, then you can make that symbol private, IF it really should be
In both cases you need to do a fairly exhaustive search for consumers.
In both cases you need to individualize the decision for each interface.
Automated static analysis is not sufficient for making these kinds of
