This can also be simulated by send a horizontal orientation to the
plugins. I think I prefer a checkbox to enable this behaviour.

My idea was to add a packing/container plugin to add for example 3
launchers in a vertical row. Is still on the 4.10 roadmap, but I'm not
sure if I can complete it mostly because I doubt it's a solution for
the problem and might be complicated to work with.

They are not used in the panel, but for plugins only. Not many plugins
inside the panel use these, but for example the menu positioning does.
Adding the dock mode here is a bad idea, because the place on the
screen does not change, I even not completely agree with the _H and _V
in there; floating and the cardinal directions would've been better;
but that's a leftover of previous versions.
Personally I love the Haiku deskbar and wouldn't mind if Xfce4-panel
could behave in the same way. It's not that complicated, because a lot
of plugins are already capable of this in some extend, but it requires
a lot of testing and tiny adjustments.
