!?!
What make you think qbs cannot be used in such environments?That all
very basic stuff to me.
- cross-compiling: Qbs support *out of the box* all "standard" OS
*and* "standard" toolchains.
- working with weird set ups: what does that even mean? That a very
vague statement.
- containerised build: any build system can run in a container, that's
orthogonal.
- build farms: Against what is the problem with build farm, i don't get it.
- etc: again, can you elaborate? that's very vague.

I've used Qbs to build a Desktop SW for Windows + MacOS + Linux, all
producing platform specific installers.
It was a breeze.
I've used it to build a 1.5 million SLOC SW, with complex build
matrix. The only reason we dropped it, was because of lack of
integration:
QtCreator is the only IDE that knows Qbs, as i reported on Qbs mailing
long time ago, Qbs won't take off without XCode, Visual Stidio, Visual
Code, Eclipse, ... integration.
And, so far, we failed at switching to CMake, the build matrix is too complex.
