How many Python users compile Python at all? :)
The point is that the default build of Python should use
the correct production settings for the C compiler out of
the box and that's what

OPT already uses -O0 if --with-pydebug is used and the
compiler supports -g. Since OPT gets added after CFLAGS, the override
already happens...
So nobody's proposing to drop that? Good! Ignore my last message then. :)

I agree - trying to step through -O2 optimized code isn't going to
help debug your code, it's going to help you debug the
optimizer. That's a very rare use case.
Not really. I don't have a lot of practice in debugging at that
level, so take it with a grain of salt,

Why do you think that the default -O2 is unwanted
Because it can cause debug builds of Python to be built with
optimization enabled, as we've already seen at least twice.
and how do you know
whether the compiler accepts -g
