4) What about the memory footprint?
A couple of megabytes.
I'd love to see a build how too that results in a couple of megabytes.
The smallest I've ever got Qt with a "cut everything out" configure is...

5199292 129564 11596 517d24 libQt5Core.so.5.6.2

4893838 212704 840 4deeb6 libQt5Widgets.so.5.6.2
This is ELF section sizes, not a memory footprint. Actual memory footprint
(RSS/PSS values) can be obtained from smaps file
A simple console only application (only using QtCore) I built using a
static Qt build without -ltcg is about 4MB memory foot print on arm...
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1129 root 20 0 14244 4004 3848 S 0.0 1.6 0:00.01 simple_app
Using -ltgc saves about 31%, so aprox 3MB memory footprint.
Using a dynamically linked Qt version, I've seen memory footprints as
low as 200K for console only applications.
