Seriously?

this is the list of "dropped symbols"

- testing_append_commands_node@Base 1.0.29
- testing_known_commands_input_failed@Base 1.0.29
- testing_last_known_seq@Base 1.0.29
- testing_record_backend@Base 1.0.29
- testing_xml_doc@Base 1.0.29
- testing_xml_next_tx_node@Base 1.0.29
- testing_xml_path@Base 1.0.29


Please find a single reference of something in the archive, or outside the 
archive, that ever used
part of such (not meant to be exported) API.

The *bug* was to export them in the previous version, not to remove them, 
because meant to be internal symbols.

We had other references in the archive history, where symbols incorrectly 
exposed were dropped without
the need to change the ABI.

We discussed many times already, few people (including I guess the sponsor for 
that particular upload), and at least
3 other DDs agreeded that there was no need to change the SONAME just because 
of something that was not really
used anywhere in the world, included self-compiled stuff.

All the RFS bugs for sane-backends are public, you can find lots of discussion 
about the topic, and help
in better developing the package.

I think this is a non-issue, I would like to have some real bugs before talking 
about the Sex Of Angels... [1]

I also think its better have one single bug, instead of having two of them, for 
the very same source package.
