Yes, _Z* are private, and are better to be stripped out.

You can, but that won't fix the object files exporting private symbols.
Instead you better suggest alure upstream to use a linker version script [1] 
[2], to control symbols publication.

Trivial example (these are public, the rest are stripped out):
local: *;

Then you can still use  dpkg-shlibdeps symbol files to determine the minimal 
required version of each dependency.
