Has there been any progress on resolving this for the buster release?
If the SONAME is not increased upstream (which doesn't seem likely to
happen soon), then the ABI break should be worked around in Debian by
renaming libdmtx0a to libdmtx0b with Conflicts: libdmtx0a, similar to
what was done for the transition from libdmtx0 to libdmtx0a. After doing
this, the release team will need to trigger rebuilds for everything that
depends on libdmtx0a.
