Stepping into optimized builds is kind of an annoyance but, at least for
me, it is much less of a pain than you make it sound. When I'm are
looking for the kind of bugs that only occur in release builds, due to
some race condition or some optimization/UB my code didn't account for,
it is _very_ handy to have the debug symbols for the officially
distributed builds. Also, the above mentioned backtraces alone are worth
every single byte of debuginfo we provide. Therefore, debug symbols for
release builds are important and QTBUG-81354 needs to be fixed.
