[Interest] How to prevent large qml forms from hitting javascript stack size?

You don't want 775k objects in memory all at the same time.

You can use the various views (ListView, GridView, ...) to dynamically 
load objects as needed rather than pre-loading them all. You can also 
use Loader and Instantiator to factor out groups of objects to be loaded 
only when enabled.

You can use Repeater to de-duplicate your code and reduce the overhead 
of processing huge amounts of it. That would initially help you here, 
but it would still result in lots of objects being created after it's 
done processing the compilation units. You may still do it for the 
internals of your components once you've split them into groups.
