That's the plan.
If the optimization levels (at least in LLVM) have names, we can
easily make -OFastDebug and -ODebug have the same "debug" flag set,
and so on.
enum OptLevel {
Debug = 1, // Debug Illusion
Speed = 2, // Performance
Space = 4, // Size
Aggressive = 8,
}
-O0 = Debug
-O1 = Debug+Aggressive
-O2 = Speed
-O3 = Speed+Aggressive
-Os = Space
-Oz = Space+Aggressive
Then passes only need...

That's correct, -g must not affect code generation. This is a
fundamental mantra among debug-info people.
