As a end user, it gives the impression that the system is shaky.
Now, this is written out of frustration: I spent while documenting a set of classes only to get the thing to a VM crash when posting to monticello and followed by the inability to get the work back without copy/pasting stuff all over again since the changes files wouldn't work (and is full of <historical> entries).
Well, that's what it has to do with each other: the workflow is broken and it demotivated me from documenting classes again. Preventing contribution is not good. Especially given the boatload of undocumented items.
