What should happen if the docked control has Align=AlClient and the dock host control has AutoSize=True, is still a source of mystery to me :)
That's why I would not implement too much automatism. An autosizing dock site sits in a common environment (form...), together with other components. Consequently it cannot enlarge itself arbitrarily, but only with regards to the other components in its parent.
When we drop the DockManager, in favor of an general layout manager, a docksite would become just another (possibly autosizeable) control. When a control is docked into such an autosize dock site, the docksite would request a recalculation of its extent, from its parent, and this request may ripple up to the outmost form, depending on the constraints of all involved controls. Then the new extent of *all* affected controls is determined, and the docksite will be told its new extent, just like every other control is told.
