I think LibO and the kernel are pretty much the only examples where I
can understand and could tolerate this. It would set a precedent which
other people can point to though, and before we know it we are in the
situation that Ubuntu Touch was in the past when people never landed
new things in the devel series first and then fixes got lost, merging
was a pain, etc.

This is the only real point in time when this gets checked by a human,
beyond that we don't have any pressure on developers any more to land
in devel first.

In this particular LibO case this argument also doesn't work -- LibO
5.1.2 already *has* been uploaded to yakkety twice, and it clearly
does build with the new toolchain. There is no reason to assume that
5.1.3 is worse, and if it is, that's a regression that should be
investigated first.

I'd say that cases like this at least require prodding some SRU team
member with some good reason -- I wouldn't expect these uploads to get
accepted as part of the regular workflow.

That said, I accepted LibO for xenial-proposed now. But these kinds of
special cases are hard to track, don't stick around, and don't
generalize.
