It appears that there were no major concerns. I will follow up #835148 and request PIE by default for the following architectures.
* amd64 * arm64 * armel * armhf * i386 * mips * mips64el * mipsel * ppc64el * s390x
Such a change will produce unneeded FTBFS's in libraries using -fPIC (such as qt5 and all it's dependencies).
Afaik, -fPIC is stronger than -fPIE, at the same time, -fPIE is incompatible with -fPIC and -fPIE makes little sense in shared libraries.
And while a single patch should be trivial, I fear they would be many specific ones.
