Correct. Layout HTML items, HTML annotations and Resource Widget with
integrated viewer all depend on QtWebkit, and will not be ported to
QtWebEngine for the foreseeable future. (It's just not possible --
QtWebEngine is missing required functionality.)

Very much so. QtWebEngine seems targeted at the simple use case of an
integrated web page viewer, vs QtWebkit which has a much more powerful
API. Specifically, the big blocker is that QtWebkit allows rendering
of webpages AS VECTORS onto a QPainter. Last I checked (maybe ~6
months ago) discussion at Qt channels was that this was
non-trivial/impossible to implement in QtWebEngine and was not being
actively worked on.
