Sure, I agree that you should limit ASIL certified software as much as possible. Nothing running on Linux will be certified ever.

That also limits the benefits of Qt Safe Renderer. I think it is mostly a marketing thing within the automotive sector. The competitors there (Disti, Kanzi, etc) have their "solutions" for safety critical and say Qt can't handle it. So Qt needs to check the box of "safety critical" to fend for themselves.

Tell tales can quite simply be implemented by hand coding. But there is OpenGL SC which possibly could support more fancy and certified graphics. It could be nice if Qt/QtCreator/Qt3dStudio supported that in some manner. Having a layer that is safety critical and separated out to it's own OpenGL SC code. The usual argument for this kind of stuff is that nice graphical ADAS features (think advances HUDs) will need this (although I think it is still reasonable to hand code it in OpenGL SC).
