Yes, so long as the package name and soname follow Debian standards you
won't break anything (until the upstream upgrade that conflicts with
the old stuff - but that hasn't happened yet, so isn't yet a concern I
think). I was merely complaining about breaking things with the
current package. It seems that if you release the new package with
soname 0, and the other packages rebuild against it, there will be
fewer problems when soname 1 is released.
