This is not how SONAME works, especially in a binary distro like Debian.
Even assuming an SONAME bump is due (which IMHO is not), the consequence
will be:
1) the SONAME of the library is bumped, either by upstream or in Debian
2) the Debian package is renamed
3) exiv2 will go through NEW
4) there will be a new exiv2 transition, and all the packages using the
   exiv2 library will be rebuilt anyway (including gthumb)
5) we are back to the same situation

This is a behaviour change of the API, and IMHO there are two only
options:
a) restore the old behaviour, optionally adding a new API if needed
b) adapt the applications to the new behaviour of the API

Considering that it seems a wanted change by upstream, then I don't
see (a) happening, so (b) seems to me the only alternative. Sure,
it is not nice, but meh, not something else to do.

Because of the above, Vincent, what about closing this bug, since there
is nothing actionable in exiv2?
