Packages that usually get built and tested with -Og should be pretty rare,
and these specific build failures are better at finding the rare packages
that use -Werror than pointing at potential miscompilations.

is changed (usually the compiler version).

-Og is better suited than the -O that was previously used for debugging,
but are we talking about debug builds or production builds?
If users would be using DEBUG_OPTIMIZATION in production builds that 
would be wrong - this will always be a mostly untested situation
with an increased probability of hitting bugs noone else has seen
before.
