In "QmlFoo", the first three letters refer to the acronym or technology name
"QML", otherwise the m wouldn't be lowercase. I don't think we want to expand
the M because the word it stands for is just marketing and has little to do
with what the language is.
To be honest, QMLEngine is better than QmlEngine.

Understood, thanks for clarifying.

Ok. How does that affect the API and not the language itself?
How big are the Qt Quick 1 language support classes? I'm asking so we can have
an idea of how much maintenance effort those classes will be. I assume that
they will continue to use V8, which will be continually updated and modified to
support Qt Quick 2 and that introduces risk of regressions and breakages.
