People previously complained about the same in SplitPanels; the
official answer is that it's deliberate, because as soon as you expose
an API, you're expected to not break it, so having everything "closed"
gives you (the GWT Team) more room for changes.
At the time, developers were encouraged to copy&patch the SplitPanels.
I don't know if the GWT Teams position is the same for CellTree and
CellBrowser, but given how young they are, I suppose it could be
(until they're deemed "mature" enough); see for instance the recent
internal changes:

(not sure they would have impacted "extension points" of the widgets,
but still)
