Hi Dietrich, I think you're close. The typical .remove() method really means that, remove the child widget from the parent control. But nothing is destroyed as there might be further references to the child that are still alive. When the parent is disposed it calls _disposeChildControl (via Widget), which in turn calls .destroy. So I figure _disposeChildControl should suffice in your context, in order to avoid leaks.
I guess the automatic handling of childControls is more geared towards compound controls where the child controls have the same life cycle as the parent. If you decouple the life cycles then it's hard to know for the compound control if you intend to further work with removed child or not, and you have to do the cleanup yourself. If you can think of a nice API for this (e.g. an optional parameter to .remove()), feel free to open a bug for it. T.
