Looking back over my previous attempt, I think you might not be
affected.  (In any case COM/ATL support would not be dropped)

It has been getting touched, but if I remember correctly we don't have
good coverage there.

I would suggest testing newer builds of LibreOffice to make sure it
keeps working as you expect.

The other problem was not having good test cases for making changes to
the code.  I do note in my original release notes "We specifically
want feedback if you use ActiveX to embed LibreOffice components into
your application."  Our original intention was to remove the plugin
that allows you to embed LibreOffice inside other applications (like
IE) using ActiveX.  Without test cases that worked, we weren't able to
ensure we wouldn't break something.

I don't currently have time to pursue this right now, but would be
interested in testing some custom builds to ensure that we remove the
right part of ActiveX while your use case keeps working?
