[PyQt] Attempting to reduce the memory footprint of my PyQt5 application

[Xavion]

Hi All,

I'm trying to cut down on the memory usage of my PyQt5 application.  I'm
assuming that one way to do this is to only import the Qt submodules that
are actually used.

The three attached files illustrate my point.  The Qt5 Designer only
imports the necessary submodules (e.g. "QtCore/QVariant").  Whereas, the
PyQt5 UIC and RCC generators import the parent modules in full (e.g.
"QtCore").

Assuming my memory reduction theory is right, is there any way that I can
get the UIC and RCC generators to behave like the Qt5 Designer?  There's
probably no point in using this strategy throughout the rest of my code if
not.
