How and when is the data in those removed/renamed blocks gets eliminated in the database? If the data stays indefinitively in the database, then we need some kind of cleanup procedure. A French user suggested the removed blocks should not be hidden and appear in the page editor, with some kind if deletion function.
I actually don't think of this as a bug. well, not too much anyways.
people regularly update templates, at least in the initial stages of design. and if in one instance of editing they remove (or rename) a content block, and then put it back in another, the content isn't lost.
However, I don't think the feature list is complete, we do need a 'cleanup' utility that will go through and 'cleanup' the content tables and get rid of extraneous, not ever referenced content.
We just haven't got there yet.
