Either integrate into installer, or ship separately, the key LibreOffice extensions.
(Disclaimer: just another user here...)
Even if it seems to be a great idea, I think it will be quite difficult to find two people who agree on which are the "key extensions".
Maybe it is necessary to first discuss how the "best extensions" can be chosen.
Hm, at least a core set is easy to determine - those that are implemented in c++, and require more or less in-sync updates with LibreOffice anyway - those should have never been made into extensions, and are best distributed together with LibO.
Looking over my bugs - this was actually fixed for beta2 already.
