I use the following rules to decide when to bump the soname:

dnl libtool versioning for libqmi-glib (-version-info c:r:a)
dnl    If the interface is unchanged, but the implementation has changed or
dnl        been fixed, then increment r.
dnl    Otherwise, increment c and zero r.
dnl        If the interface has grown (that is, the new library is compatible
dnl            with old code), increment a.
dnl        If the interface has changed in an incompatible way (that is,
dnl            functions have changed or been removed), then zero a.
m4_define([qmi_glib_lt_current],  [5])
m4_define([qmi_glib_lt_revision], [0])
m4_define([qmi_glib_lt_age],      [0])

Then the -version-info in LDFLAGS is set as:
    -version-info
$(QMI_GLIB_LT_CURRENT):$(QMI_GLIB_LT_REVISION):$(QMI_GLIB_LT_AGE)

Is that process not right?

Yes, yes, we could definitely do that. I don't think we can change the
soname back to the old one, though, even after the change :/ I'll try
to change the approach for every new release, even major updates, and
always try to provide backwards compatible symbols whenever possible.
