LibreOffice SRU for Focal

[Brian Murray]

The unapproved queue of Focal currently contains an upload of
libreoffice[1] which is "a bug-fix release of the 6.4 line"[2]. However,
as I understand it this update switches to tracking a different upstream
branch of LibreOffice. As such I'm not certain this still meets the new
upstream microrelease criteria[3] which has been used for previous
libreoffice SRUs. We certainly want to be able to update libreoffice for
the LTS on a regular basis, but I'm concerned about whether or not the
mimo branch is getting the same level of upstream quality assurance.

I know that sil2100 had some concerns about this change too[4] and I
think we need to come up with a solution so we can continue to provide
updates of libreoffice for the LTS.

Does anybody think this continues to fall under the standard upstream
microrelease exception?

ricotz - Can you provide any additional information about the upstream
testing of this branch?
