[Development] 5.7 feature freeze

I am sure I am not the only newcomer to QT who would love to add code
to the 5.7 feature list,
but barely have time to contribute bugs to debug 5.6.0 beta let alone
look ahead to 5.7

Now we are faced with waiting until 5.8 to even think about a set of
key missing functions in Qt QML.

I am still firmly planted on the interest list and not on the development list.

One major problem lies with QQmlEngine design:

It has the following functions defined:

QQmlEngine->clearComponentCache()  (https://bugreports.qt.io/browse/QTBUG-50500)

But it is absolutely missing:

gcomp) -> error code
QQmlEngine->removeComponent("MyComponentLib",1,0,"MyComponentName") ->
error code
QQmlEngine->isComponentLoaded("MyComponentLib",1,0,"MyComponentName") -> bool

Devs are stuck using a QMLDIR file based import pattern that has the
flexibility of an ice cube.

We really need qml files to be able to execute: import MyComponentLib
1.0 without using QMLDIR files!

The other major problem is that QQuickItem does not allow for
QSGTextRect, so updatePaintNode CANNOT have text rendering
in coordination with QSGGeometry.  The current recommendation is to
try to coordinate using signals between 2 different QQuickItems, 1
with text, the other
with graphical geometry.  This is a restriction that appears to have
occurred by chance.

This cripples custom controls capabilities and forces me to explain to
customers about Qt limitations.

So how can we get the header file for QQmlEngine changed for 5.7
feature freeze to add those 3 function declarations and un-sandbox
and still pass maintainer acceptance all by Monday?
